Last week I thought I'd lost my Apple iPhone but after a day I found it. Still, I've become a bit paranoid, but having a security code on the phone itself is too annoying. Instead, is there a way for me to remotely set a security code if I do lose the phone again?

Every so often I get an email message on my iPhone 3GS and want to save it for later, rather than have it vanish as it's replaced by newer messages in the mailbox. I can't see any way to save it, though, other than in folders, and I have a feeling I'll just forget what's there. Is there a better solution?

Imagine a device that's about the size of three credit cards and can let you and four of your friends (or multiple of your devices) connect to the Internet at decent 3G speeds, all while sitting in your briefcase / computer bag / coat pocket. The up-and-coming "mifi" (mobile wifi) devices are a fascinating hybrid gizmo that offers the smallest wifi base station you can imagine, tapping into either the Verizon or Sprint data networks.

Verizon loaned me one of their mifi-2200 units and I have to say this is a fabulous gizmo, one that I'll find out about buying when my loaner period is over. It's that good.

As I said, the device is tiny: even in its little cloth pouch, it's less than half the size of my Apple iPhone, and considerably lighter. It uses a micro-USB connector for both charging and direct connectivity (if you prefer to use it as a tethered cellular data network modem), so it's also extremely portable. I know I've gotten into having it in my computer bag 24x7.

When sending mail from Apple iPhone 3GS my copy says from barber This is incorrect. How can I correct this? Thank you! Barbara

I park in various lots downtown when I have meetings there, and, well, sometimes I forget where I parked. I started out taking a picture of the front of the parking structure with my iPhone 3GS, but suspect there's a better solution. HELP!

I'm psyched that after months of waiting, AT&T has finally announced that there's now multimedia messaging service (MMS) available on the iPhone 3G, but, darn it, I hooked up my phone to my computer but it didn't say there was an update. So how do I get there, how do I enable MMS on my Apple iPhone?

I watched the latest Apple announcements and was pretty impressed by the different things that Steve Jobs talked about, but the one that caught my attention was the iPhone Application Genius recommendation service. I'm a bit of an app-aholic, so I like to see what's new, but with tens of thousands in the iTunes app store, well, a recommendation service seems like a great idea. How do I use it?

Now that GPS apps like Tom-Tom are showing up on the Apple iPhone 3GS, I'm wondering if I really need to buy those expensive apps when Google Maps that's included with the iPhone does such a great job? I know I can get directions, but can I get turn-by-turn directions like I would in a handheld GPS?

I'm borrowing a colleague's tiny little Verizon wireless cell modem gizmo, the MiFi 2200, and I'm totally impressed with it, except for one huge thing: what the heck do the lights mean?

I don't know if this is even possible, but my girlfriend keeps sending me cute pictures and when I read them on my iPhone I really wish I could save them and use them as wallpaper images. Is that even possible on the iPhone, or do I have to get my computer involved in the process?

What a gaffe! I wanted to get more information about the new TomTom turn-by-turn directions application for the Apple iPhone 3GS and clicked "Buy App" instead of the icon for the app. Next thing I know, I've just paid $99 for this app and it's downloading onto my computer. Not good, not good at all! What can I do?

I just recently downloaded the game "Besieged" for my Apple iPhone but am stumped, unable to get past the last boss. Is there some trick or walkthru or something you can point me to, Dave?

If you've owned an Apple iPhone 3GS, 3G or still have an original iPhone, I don't need to tell you that one of the constant hassles with the phone is battery life. It's better in the newest phone, but everyone who has an iPhone seems to have their own strategy for minimizing battery usage, ranging from "don't use the 3G network" to "disable wifi" to "turn off everything, especially bluetooth".

I leave everything enabled on my phone except Bluetooth and my adaptation strategy has been to have lots of power cords with me: two in my house, one in my car, and one in my computer bag so I can sip at USB power whenever I'm using my computer on the go. It's a hassle, but it's manageable.

Where this breaks down is when you're at a trade show or out for the day, without the chance of getting near a power plug, computer or vehicle. You've seen it at parties, i bet: people making BFF's because they have the ability to quick charge iPhones, huddled by the wall outlet like it's the illicit drug of choice.

It's no surprise that add-on and extension batteries are a popular accessory for Apple iPhones, and six months ago, the major contenders were awkward battery devices with universal plugs that acted like an external gas tank: useful if needed, but clunky as heck.

The newest generation of these devices are sleek and double as iPhone cases, and two of the best are from Tekkeon and Mophie.

Do they work, though, and how do they compare? Read on...

A buddy of mine was showing me how on his iPhone he has a tiny percentage display of how much battery life he has left on his iPhone, in addition to the usual battery graphic that's displayed. But he wouldn't show me how to get it on my phone. Before I do something drastic to him, can you tell me how to get that to show up?

I use Mobile Me with my iPhone now, and am finding that the gallery feature is pretty cool, but it's tedious as heck when I have to upload them one at a time. Isn't there a smarter way to do this on my Apple iPhone 3GS?

I'm sick of tapping into wifi signals where I can find them and being stuck without any Internet access when there isn't one, or when it's password protected. So I sprung for a Verizon Mifi2200 device that they tell me will met me connect from my MacBook Pro to the Internet anywhere, any time. But how do I get it all set up on my Mac?

I'm a big fan of Apple gear, like you are, and while I've been an iPhone owner for quite a while, I've always been pretty leery about paying for the Mobile Me service. Apparently, though, one of the slick new features is the ability to always find your phone if it's otherwise lost, called "Find My iPhone" or "Find My Phone" or something like that? Coolness. Can you show how it works?

Now that I have an iMac and an Apple iPhone 3GS I am thinking I should also sign up for Apple's Mobile Me service so I can have wireless syncing and be just a bit safer in case I lose my phone too. How do I proceed?

I've started reviewing Apple iPhone games and just had a game developer tell me that he'd like me to check out his game and sent me a promo code. I'm a bit baffled by this: how do I redeem a promo code for an iPhone application so that I don't have to pay for the game?

Thanks to your articles and some experimentation on my part, I have figured out how to make videos on my new Apple iPhone 3GS. My question is: how do I upload these videos directly to YouTube as I keep reading you can do?

One of the cool new features of the Apple iPhone 3GS is the ability to take videos. Nice, but I can't figure out how to get to the video camera? I know how to take photos, though, so I figure it's related to the iPhone camera (rather obviously, eh?) I have also heard that you can edit the video right there on the iPhone, but I don't believe it. I mean, isn't the screen too darn small?

Okay, since you wrote about Spotlight on the new iPhone OS 3.0 (see How to work with Spotlight on your Apple iPhone 3.0), can you also explain to me how the heck the new Voice Memos application works? As far as I can tell, it's the only other new app included in Apple's iPhone 3.0 upgrade but I can't figure out how the heck it works...

I finally updated the operating system on my second generation iPhone and the new OS is definitely cool - and faster - but I'm not too sure how to use Spotlight, the search feature that so many people have been talking about on Twitter and elsewhere. What does it really do for me and how do I get to it?

I love that on my new Apple iPhone 3G I can flip a switch and turn the phone from ringing to muted so I don't bother people. Problem is, the darn thing vibrates like a sex toy and it's still annoying in meetings and at meals. Is there some way to disable the vibrate feature too? Thanks.

This is just the weirdest thing: I got a new Apple iPhone after my old one broke and now when I hook it up to my iMac, it sees the phone, but I can't copy the photographs off the camera. In fact, there aren't even thumbnail preview images when I check with ImageCapture. What's going on?

In his sermon last weekend, our pastor talked briefly about the dangers of our teen children sexting. He didn't go into it and I've no clue what it's all about, but I want to know more about sexting before I talk with her so I don't seem completely clueless. Help?

The Japanese and American cell phone markets are opposite like lamb and tuna fish. That was one of the first things that I noticed when I spent a few weeks there two summers ago. I've always had a less than optimal view of our cell phone market's infrastructure where the best network gets the ugliest phones and the worse network gets all of the good looking phones but without the reception. That's why when I went to Japan and saw that multiple companies had summer cell phone lines coming out like seasonal clothing lines, I was taken aback.

I was used to a network here where my phone's novelty wears off within the hour that I get it, and then I'm trapped in a contract for far too long with expensive escape fees. In Japan though, I could customize my plan (daytime only service or TV reception for example) with a good looking phone and solid service even underground in subway stations, according to Japanese cell phone customers.

If the cell phone world is so perfect in Japan, why is it so fundamentally flawed here in the States? Why is it so rigid, straight forward and uncompromising? Why as consumers haven't we demanded the flexibility that the Japanese cell phone industry exudes?

Google is one of many companies that's been pushing the various capabilities of mobile devices and exploring how to make its vast storehouse of search data accessible in novel and interesting ways to people with the G-1 (the so-called Google Phone) and the Apple iPhone.

The latest example is Google's introduction of its mobile shopping interface, officially called Google Product Search for Mobile. If you never search for products for sale - probaly to do some comparison shopping - you might never bump into it, but it's pretty cool.

Let me show you...

I'm just starting to get up to speed with Google's slick Google Voice application and have heard that you can use it to make free or at least pretty darn cheap international calls. I'm psyched! My brother is in Sweden and we rarely talk because of the cost of long distance. How can I gain access to the cheap international calling with Google Voice?

I love my shiny new iPhone, but I'm totally concerned someone will steal it, find all my personal information and steal my data.  What can I do to prevent it from being lost?

I've been hearing a lot of buzz about the new Skype for the iPhone 3G, but am a bit lost about how to download specific applications onto my phone. Can you show me all the steps?

I've been using my Apple iPhone 3G for a few weeks now and am pretty darn impressed with all it can do and with the zillions of apps in the iTunes Application Store. This afternoon, however, I saw someone else who had completely reorganized the app icons on his home screen. I want! How do I do it?

Just heard about the slick Skype for iPhone and want to get it and install it. Well, I can get it by downloading it from the App Store, but can you step me through configuring the Skype application so I can start using it ASAP?

I don't know how it changed, but suddenly the default search engine on my Apple iPhone 3G is Yahoo, not Google. Now I like Yahoo as much as the next guy, but I really want Google back. How the heck do I change the default search engine in Safari??

Hi Dave. I'm hugely enamored of the Google Maps feature on my Apple iPhone, but there's one thing that baffles me: how do I reset the "current location" as a starting or ending point when I'm using the phone for directions?

What the heck, I got a note from Apple that I need to update my carrier data on the Apple iPhone? What's it all about?

i have a problem with my iphone 2g 8gb. the phone was working just fine, until i downloaded the call me application from cydia, i turned off & now it wont turn fully on, the screen only freezes showing the pineapple, tried pressing both buttons & holding the initiation one, nothing.. what can i do?? does it still work?

If you're highly mobile, if you travel to trade shows or just walk around campus all day, or perhaps if you take long plane flights, you already know that for all the great features of the Apple iPhone, extended battery life ain't one of them.

Indeed, when we recently attended the 2009 Consumer Electronics Show it was by the end of the first day when it became apparent that the iPhone just didn't have the battery longevity we needed.

That's why we decided to test out extended iPhone compatible batteries at the show, seeking out vendors and asking them for samples and demo units. Most of them were not very good and I'll note that when I tried one that was powered by a pair of AA batteries it died before even completing a single charge. Useless.

Fortunately, I did find one that I was very impressed with, the Power Air Zpowerpac13 and have subsequently been sent a second that's also very good, the morphie juice pack.

I've gone through an amazing number of iPhone cases in the last year or so, between the ten or so I reviewed for the first gen iPhone and the cases I've been sent for the newer 3G phone. At first, my iPhone cases of choice were the rubberized ones like those from InCase Designs. (they call it a "form-fitting, injection molded material", of course, but to me it's just a fancy sort of rubber)

Then I realized that since I like to slip my iPhone into the front pocket of my pants, I'd often end up with the case collecting lint. Not so good, so I moved to harder plastic shells, but didn't really find any that I loved. Well, I like the Griffin Wave for its mix and match capabilities, but not enough that I haven't kept looking.

Until iFrogz generously gave me a couple of their 3G Luxe cases. What can I say, these just ROCK!

I've been reading all of your extensive iPhone help on the site and found it a great boon to learning how to do things. I can't find any info on how to set up my phone to require a code be entered before it'll unlock, however. Do you have information on how to lock an Apple iPhone?

So I want an iPhone but AT&T’s service is just too expensive! There must be a better way! I have a Windows PC not a Mac, by the way. Do I need a Mac running Mac OS X to unlock my phone?

I found "Image Capture" (you didn't mention it was an application, so I searched and found it) and tried what you suggested. When I click on download, however, nothing happens. Tried this with just one photo selected, as well as "Select All." Any suggestions?

I got a text message from AT&T telling me that I can now connect my iPhone up to the AT&T wifi network at Starbucks for free. Nice, but I've heard it's convoluted. Can you document it so I know how things should proceed?

I'm going back and forth on whether to spend the money and buy myself an Apple iPhone. In a lot of ways it seems like a very cool phone, and certainly it has far more features than my clunky old LG. I know about the core functions, but my first glance at the iPhone Application Store was totally overwhelming. I mean, there are HUNDREDS of applications. Tell me, what are your favorites and do you stick just to free apps, or have you bought some too?

My wife and I have a series of ideas for Apple iPhone Apps, but are not even close to programmers... What would you recommend for us? I am trying to start with writing a document that outlines the Apps...games. From there, do we just turn it over to a programmer? Do we need to worry about property rights, etc.?

Okay, so your article yesterday about Genius playlists in iTunes (see How to Create Genius Playlists in iTunes 8) has me intrigued and I'd like to experiment with it. But on my iPhone. Is that a possibility? That is, can I create a Genius playlist on my iPhone 3G or, I suppose, on an iPod Touch?

I really love Miley Cyrus and want to turn her great song "Life's What You Make It" into a ringtone for my Mom's cellphone so that when I call, she hears Hannah Montana (well, Miley) singing, letting her know that it's me. I've heard that's not too hard but have no clue how to proceed.

I love my iPhone and have been having all sorts of fun playing with it. What I want to do, however, is assign custom ringtones for some of my friends. Ultimately, of course, I'd like to have specific songs for specific people, but even just having the ringtones that are included with the phone assigned would be cool.

I've been reading your cool iPhone app developer series on your business blog and am inspired to dig into the Apple iPhone SDK and write a few games. I'd love to charge a few bucks for my games, but want to make copies available to my friends for free. Is there any way to do that?

Man, it was one of those crazy moments. I realized a split second after it was too late that I'd just driven over my cellphone. I checked it out and, surprisingly, the phone didn't seem damaged at all, except it just won't turn on. I called AT&T and they told me that it'd cost $99 to replace it and that I couldn't cancel the cellphone number because my contract wasn't up. Augh! What are my options at this point?

I just bought a new 3G Apple iPhone and now want to give my old iPhone to my brother-in-law. He's even ready to pay for it. Problem is, I want to wipe it clean so he gets a pristine phone. How do I do that?

I am old enough to remember when all you could do with a phone is make a call…heck I remember rotary dial telephones. I think my parents' were the last in the state to get with touchtone. I kept teasing them that the Smithsonian is going to come and confiscate their rotary phone.

In the 80's, I had one of those "mobile phones" there were the size of a loaf of bread, and weighed about the same as a third grader. But I was cool, listening to Depeche Mode and driving my 1971 Plymouth Fury. Risking hernia or concussion every time I used my "mobile phone".

Fast-forward to 2008....

I have a couple of movies in iTunes that look great when I view them on my computer, but when I copy them to my new iPhone, I can't watch them: the phone complains "format not supported". How can I fix that?

I just heard that there's a software update for the Apple iPhone 3G. I want it! But I'm confused: how do I update the software on my phone?

I just upgraded from a first generation Apple iPhone to a shiny new 16GB white iPhone and am excited to switch over completely. All my data, phone book, etc are on the old system, though, and I am perpetually anxious about first sync as I'm afraid that the empty phone address book will overwrite my huge address book data already on the computer? How do you clone the old iPhone and the new?

Now that I have a shiny new iPhone, I've gone a bit wild adding applications from the iTunes Application Store. So many applications that it's out of control. Now I want to delete some, but each time I delete them on the iPhone then hook the phone up to the computer, they reappear! :-(

I'm excited to add the many new capabilities and improvements to my beloved Apple iPhone, but have heard that the jump from 1.1.4 to 2.0 completely wipes your phone. Can you show me how to step through this firmware upgrade and reassure me that my contacts, photos, music, etc will all be there on the other side?

I just downloaded the latest version of iTunes, all excited about being able to finally get to the Apple Applications Store and grab some new stuff for my iPhone, but when I restart, it's not there?!

My iPhone is being very weird: when I plug it into my iMac the computer doesn't seem to recognize it any more. How do I fix it so I can be a happy iPhone user again?

I have a RAZR with Verizon and keep lusting after the Apple iPhone. Now that they have a new 3G phone coming out, do you think I should terminate my contract a few months early and get one?

I've signed up for Twitter and am having lots of fun with it, but every time I add someone new, all of their Tweets end up going to my cellphone as SMS text messages. This is bad, and it's driving me crazy. Is there some easy way to fix this?

My digital camera has a cool feature: it can take little movies. They're not as good as a real video camera, but my kids love mugging for me and the results are often quite hilarious. Like "America's Funniest Home Videos" caliber. How do I put them on my Apple iPhone so I can share them with my friends?

I had my old Mac laptop, an iBook, stolen and now that I have a new one, I realize that I can't get the music off my Apple iPhone which is driving me crazy! Is there some way to sync the iPod music and video portion of my cellphone without having to start from scratch again?

I am a big fan of my Apple iPod, but I can't figure out how to have it automatically download the most recent podcast from the podcasts I subscribe to. I think there's something I can do in iTunes to get this to work, but I'm just not exactly sure how to proceed.

Saw your earlier note about creating custom Apple iPhone website icons and think it's very cool, but I'm wondering: how did you delete the icon you didn't want to keep?

One of the features added to the latest revision of the Apple iPhone operating system that's garnered quite a bit of attention is the ability to save Web page bookmark icons directly on the main screen of the phone. Experimentation reveals that some sites have cool icons while most are just miniature representations of the Web site. What's the difference? Read on and find out, including step-by-step directions on how you can easily ensure your own site (or blog!) has a custom iPhone icon too.

I have heard that in Japan people use their cellphones as simple payment devices, even for vending machines, which sounds super cool. Here in the US, though, seems like there's not much at all I can do with my phone. Is there a service that lets me send money to my pals, for example?

It was about four months ago that my 4GB Apple iPhone showed up and, after an initial scare that it was broken from dropping it - screen down - on a hard tile floor, connected to the network, replacing my Blackberry Pearl. I got the $100 credit for the Apple store after having watched the price drop $200 a month after I bought it, and I've gone through a number of cases already (!) and have a stack of different ones from the folks at Marware that I'm using now.

But after months of having it in my pocket, plugged into my car, on lunch tables with colleagues, and in various cities and states throughout the United States, what's my opinion of the phone now? What do I really love about it, and what drives me batty?

Read on...

I just upgraded my G5 mac to the latest Leopard software and am leery about syncing my iPhone with my computer because I'm afraid I'll lose data. However, I really need to get the photos off the phone and don't want to email them to myself, one by one. Your suggestion?

Maybe I'm the one dim bulb in the chandelier, but why do so many people want to unlock their iPhone, and for that matter, what does it mean to unlock the phone anyway? I can't read any Apple-related Web site nowadays without 25% of the news being about this, that or the other person who figured out some way to unlock the phone?

Okay, I read your tutorial on how to chop out a segment of a song to create a ringtone in mp3 format (see how to extract an mp3 snippet as a custom cellphone ringtone). Now I'm ready to actually find out how to copy that to my Apple iPhone and then set it as a custom ringtone. Can it be done?

I have a ton of mp3 format audio files on my Mac OS X system and want to chop a short segment out of it to use as a custom ringtone for my Apple iPhone. What's the solution?

I have a new Apple iPhone and have been greatly appreciating all your iPhone help, but am still a bit baffled by one thing: when I send mail from my iPhone, I can see how I can Cc myself, but then I see my own messages in my [Microsoft] Entourage mailbox. That's daft. Is there some smarter way to set things up?

I have an iPhone and appreciate all its features but one: I can't use the calendar capability because I use Google Calendar, not iCal on my Mac. Is there some way that I can either manually or automatically synchronize Google Calendar with iCal?

I know I can go to the Apple iTunes Store and buy movies to download onto my iPhone at a rather painful $10-$15 per movie but there are two problems. First, the selection is extremely limited, and, worse, I already own tons of DVDs. Between my Mac and PC, surely there's some way to copy one of my favorite movies onto my iPhone so I can watch it on the go?

My new iPhone is the belle of the ball. In fact, it's a problem: everyone who sees it picks it up and starts playing with it. Is there some way I can enable a security code or password so that only I can use it when it wakes from sleep?

I would like to know how to configure my Apple iPhone so that I can check my Google Gmail messages whenever I'd like. What's the best way to do this?

Just got a new Apple iPhone and bought a movie from the Apple iTunes Store so I can watch it on the phone, but it fails with "computer is not authorized to watch this movie", even though I bought it and originally downloaded it on my Mac. What the heck? How do I authorize my computer?

I'm stumped. With my iPod I simply drag and drop the music I want to take with me from my library onto the iPod on the left side of iTunes, but my Apple iPhone doesn't allow me to do that. How the heck do I put songs on the iPhone without synchronizing my entire (massive) music library?

I have a new Apple iPhone and am having fun with it, but I can't figure out how to download photographs or pictures onto it. Is there some trick or technique? Also, in case it makes a difference, I don't use iPhoto to manage my photo albums.

I'm psyched by all the hype and enthusiasm and am seriously considering buying a new Apple iPhone when they replenish their stock here in San Francisco, but I'm curious: do I have to go to a Cingular/AT&T store to activate my iPhone? I am already a Cingular/AT&T customer, if that makes a difference...

I spent a fair amount of time on the phone with Leslie Brooks Suzukamo, Telecom, Technology and Energy Reporter for the St. Paul Pioneer Press. Our topic of discussion? Whether the new Apple iPhone is going to be a good business phone or not. He quoted various industry sources and so-called pundits who predicted that it wouldn't and that it's designed exclusively for consumers. But he -- and they -- are so terribly wrong...

I saw your entry about how to filter incoming Blackberry email so you don't drown in the trivial, but I have a different question: how I can set up a vacation hold, a way to completely disable all email notification without actually shutting down my account? I'm going on a long-weekend to Mexico and don't want to pay data roaming charges for email I don't care about anyway!

I don't get it, I have a new Blackberry Pearl and have been enjoying getting used to its predictive typing system, SureType, but all of a sudden my phone is now into the same annoying multiple-keypress input system that my pre-Pearl phone forced me to use. How do I switch back to the predictive SureType system?

Since you seem to be delving into the world of the Blackberry Pearl with your Mac system, I was hoping you could tell me how to use the Pearl as a wireless (bluetooth) modem with my Mac OS X Powerbook system. Didja figure that one out yet, Dave?

I just bought a Blackberry Pearl, figuring it's the best phone out there until the Apple iPhone arrives, and am pleased with its ability to "push" email out to me anywhere, tapping into my main email account. Problem is, lots of my email is from lists where I don't need to actually be notified in real time, they're just for me to file for later. Can I filter or otherwise tweak Blackberry email on my Pearl?

I just got a shiny new Blackberry 8100 Pearl phone and it's all working fine, except I am hitting an error when I try to use Google's Gmail mobile app: "net.rim.device.app.systemControlledAccessException: Missing RCC signature. Not allowed to access Certicom functionality." What the heck does that mean and what do I need to do with my Cingular Pearl to get it working with Gmail?

Dave, when we were having lunch a while back, you told me the other day that the only way to turn off the text alert was to turn off the sound on your RAZR phone, but I didn't believe it, so I asked Verizon about it. They said I can do it with Menu > select Settings > select Ring Styles > highlight Style Detail > press Change > highlight Messages > press Change.

Like just about everyone else in the United States, I now find myself with two phone lines, my business office line and my cellphone. After talking with a representative at the telco monolith Qwest, I have signed up for something they call "call forwarding" because I think I can use it to forward my business line to my cellphone. Only one question: how the heck do I actually do that?

I bought a cute little green Migo phone from Verizon for my daughter, figuring that it wouldn't be abused or sidetrack her too much during school since it doesn't have a camera, mp3 player, sms capability, etc. Frankly, it's just a four button dialpad. Nice, cute, she loves it, but I can't figure out how to program the $#@$#@ speed dial numbers on the Migo!

I'm just about to buy a new mobile phone and I don't know if I should get my phone on a plan or on prepaid, which is better and cheaper? Can you offer up some advice, please?

Hi i brought a new Samsung sgh-d500 mobile phone and i can't put music on my mp3 player. I need to know how to put music on my phone from the computer but i don't know how. Can u please help me? Thank you!

I'm frankly baffled. My new Motorola RAZR v3m is a great phone, but when I try to hook it up to my computer via bluetooth I don't see any of the file navigation services you show in your tutorials. It appears that I'm missing some sort of feature and really want to know how to turn it on so I can grab photos off my camera directly. Any tips?

I really want a Gmail account from Google but can't find anyone that has an invitation! So I'm looking at the Gmail home page and notice that it indicates I can sign up by just having a mobile phone. Well, I have one of those, so I'm hoping you can tell me how to get a Gmail account through my cellphone?

I have an ancient Palm V device that I've been thinking of tossing into the junkheap of old computer gear, but someone told me I could actually run Linux on it. I find that unimaginable, but hey, I have time, is it possible? And if so, how the heck do I do it?

I have a Motorola RAZR (V3c) with U.S.Cellular. How do I set up the alarm to ring daily without haveing to set it each day?

I have the razr phone from verizon. On the bottom tool bar there is an icon of a man as if he is speaking I am thinking this means voice command. How do I get this icon off my bottom toolbar. I got it on accidentally when I was fooling with the phone. Thanks so much!

I once saw someone show a short movie clip they'd downloaded onto their Nokia mobile and ever since have been trying to figure out how to do that on my own phone. Nokia's not much help, though, but since I saw you have some other stuff about cellphones, I thought you might have a clue?

I read your earlier note about changing the Nokia ringtones, borrowed from Yuan's Nokia Smartphone Hacks, and thought it was pretty informative. Thanks. Now, my question: can I customize the wallpaper on my Nokia cellphone?

I need some help on getting ringtones on my motorola v710. when i went to the store to get some ringtones, the guy said he cant get it on my phone. he was using mobilephone tools or something. he said there was supposed to be some MUSIC tab on the program he was using. why is it?

My wife was a sweetheart and gave me some way cool new toys for my birthday, a Motorola SLVR iPod cellphone, and the latest of the Motorola bluetooth headsets, the H700. They're both darn cool, but I can't figure out how to get them to pair. Can you help me out?

I love my Prius. I also now love my new Moto SLVR cell phone. They both speak bluetooth, but I'm darned if I can figure out how to link the two together. Can you help me out? I realize you might not have a Prius but maybe you could sneak into a Toyota dealership and take some pictures? :-)

I just got a new Motorola SLVR cellphone from Cingular and it's very cool, but somehow I can't figure out how to use the iPod area of it. How do I hook it up to my Mac and download some songs onto it, and, for that matter, how many songs can it hold anyway?

Dave, can ya help me out? I can't pair oakley Razrwire with my RAZR v3c, though it seems like since they're both from Motorola it should be pretty easy to get it working. Help!

I have a Sanyo mm-5600 cellphone but i cant get it to play the music that i download on to it. Can you offer me any advice or assistance, please?

This is a weird question, but I seem to recall that Paypal used to have a feature where I could "beam" money to someone else with a cellphone, but when I go to the site today, I can't find anything about it. Is there any way to do this?

How can I copy a DVD from my G4 powerbook (I have pocketmac pro) to my I-mate Jam phone which uses windows Pocket PC? I'm familiar with Mac the Ripper but I don't know how I can convert the files to ones that my phone can read, I'm really confused regarding what mp4 setting to use (most available softwares are for ipod conversion eg. MovieToGo)

I'm sure there's a way do to this: how do I assign a different ringtone to specific people on my new Motorola RAZR v3c cellphone? I have Verizon service, if that makes any difference.

Well, it appears that I have forgot the password to reset all my settings on my samsung d500 phone. Help!

Dave, can you record voice records and apply them as ringtones in the Motorola RAZR V3?

I dunno, maybe I just make things difficult for myself, but I just bought a Motorola HS820 handsfree bluetooth headset to use with my new Motorola RAZR cellphone, and I can't get the silly thing to work with my phone! I follow the directions, but the headset is never seen by the RAZR?

I have a SAMSUNG D500 and I recorded a song but it wont let me use it as a ringtone how do i do it!!?

This might be a bit too specific, but I can't figure out how to have my PC see my new Motorola RAZR V3c via the bluetooth system. My PC has bluetooth, but it never sees the phone. Suggestions?

Dave: I can't get my V3c voice memo tool to work. I upgraded from a Motorola V710 which had an easy two-step process for recording and listening to voice memos. The V3c allows me to record (over multiple steps), but then I can't find where/how to listen to my memos! I know this is a 'low on the radar' issue, but any insight would be appreciated.

I just heard that Google supports SMS, which should theoretically mean that I can do really easy Google searches from my Nokia cellphone. Is that true? And if so, how do I do it?

Dave, I'm very excited. I just bought a brand new Motorola RAZR V3c cellphone and it's as cool and sexy as can be, but I'm now wondering what I can do with the bluetooth capability. How do I use this thing to copy pictures up and down from my Mac to the RAZR?
