I might be the only iPhone owner who doesn't know this, but how do I actually buy and download an app for my new iPhone 4? I know the ads show it being super easy to get apps, but they don't show you how to actually do it. Help!

I take tons of pictures with my iPhone and upload them to Facebook, Google Plus and Flickr. Nice. But what I'd like to do is some rudimentary cropping and color correction since sometimes they're not quite what I want. Suggestions? I have an iPhone 4, not a 4s.

My kids are a menace. At least, they are when they get their hands on my iPhone and iPad! Well, now that I think about it, they're just all-around menaces. :-) I'd like to add some sort of restrictions to my iOS devices so that they can't just go and buy stuff willy-nilly. This is possible, right? How do I enable content and purchase restrictions on my iPhone and iPad?

I love Starbucks and go there all the time. It's no surprise that I like the slick Starbucks app for my iPhone too, it shows me the closest 'bux and also manages my gold card, letting me swipe the phone to pay for purchases and track drinks so I get those lovely free drink after 15 cards. Problem is, my son snagged my phone last time we were at Starbucks and promptly bought himself a new thermos and a bunch of VIA, which I didn't find out about until I saw my balance drop precipitously. Is there some way to prevent this from happen, to add a password to the Starbucks app itself?

My iPhone and MacBook are constantly connected, and with the advent of wireless sync in iOS 5, even when they're not connected, my phone still stays in sync with my computer data, which would be a life saver if I ever -- horrors! -- lost my iPhone.

But most people who have iPhones don't sync very often at all, and a surprising number of iPhone owners have never sync'd their phone to their computer.

That's the old school vision of your cellphone as a standalone device that works or dies, and there's no way for you to interact with it on your computer or in "the cloud", so I completely understand people who go from a Motorola or a Nokia device to an iPhone and use it the same way.

The problem is, what if their phone gets broken or they lose it? What happens to the photos they took on the device? What happens to their contact list and address book?

Enter the simple, ingenious iomega SuperHero Backup & Charger for iPhone.

Everyone keeps telling me how they find all these great bargains and deals by using the location features in their iPhones, but I have an iPhone too and I have no idea how to find any of this stuff. It's a phone. What am I missing?

Hi Dave. I've seen your earlier article on how to tweak my text message notification beep [see iPhone beep repeatedly on new text messages?] but now that I'm running iOS 5, it no longer works. On iPhone iOS5, how can I change this notification setting?

I spend a lot of time surfing the Web on my iPhone 4 and sometimes want to share what I find with my administrative assistant. On my laptop, I can just copy and paste the URL, but in Safari on my Apple iPhone, I can't seem to do the same without a lot of hassle. Is there an easier way to share a Web page address on the little gizmo?

I spend way too much of my life in meetings and sometimes it'd be very helpful to be able to make an audio recording or "audio memo" of the meeting. I have an iPhone 4s and my husband has an iPhone 4. Can either / both of them record audio or do I need to get a dedicated recording device?

I have a Personal Hotspot set up with my iPhone 4 via AT&T and it's very nice, but I have heard that running it as a wifi hotspot actually eats up battery, so I'd like to use it as a tethered USB connection because it'll also charge my phone at the same time. Is that possible, and if so, how do I set it up?

I've never seen this before, but on the icon for Messages on my iPhone 4, there's a small white exclamation mark in a red circle. Not a number indicating how many new text messages I have, but an exclamation mark. Apparently that shows up when something failed. Now what??

My sister sends photographs in the text messages she sends me from her iPhone, but on my iPhone I can't see how to do the same thing. Is there some trick to this, or something I need to enable on the iPhone to text message photos? Or is it something I need to sign up for with AT&T?

Sometimes when I'm browsing the Web on my Apple iPhone 4, I bump into a Web page that I'd like to send to a friend or two via text message. I know that there's a way to email someone the URL of a page I'm viewing, but how can I just get the URL into the copy/paste buffer so I can paste it anywhere?

If you ever wondered what techies did BEB -- Before eBay -- to find the coolest "used" technologies, widgets and gizmos, they simply traveled to a local Hamfest. A Hamfest, for everyone who missed this rare sub-culture gathering of the Ham amateur radio generation[s], it is a massive second hand technology fair, occurring nearly every weekend during warm weather. My father would travel for miles to attend; anything to be surrounded by the old "junk" that was sold to other hams, engineers, hobbyists, anyone who sought out motherboard key chains or electronics equipment that seemed 100's of years old to me. But to my Dad, this was nirvana. Someone else's adventure and inventions became my Dad's treasures.

To "appease" him I would tag along, but I never knew how much of an impact those fairs and that time with my Dad would have on my life until recently. I can trace back my love for technologies and gizmos to those Sunday mornings basking in the hot sun, hanging out with my Dad and rummaging through the broadcast isles and WWII surplus. I expanded my knowledge of old equipment, hardware, inventing, and my father. Now I truly understand the old adage, one mans junk is another's treasure. When my father found something interesting, perhaps something like a $40,000 spectrum analyzer that needed a bit of work that he could buy for pennies on the dollar, he'd tell everyone about his find, why it was so great and why we lugged it home.

Years later, when I find a product that impresses me I spend all my time in a similar fashion trying to share the good word with all who are interested. For instance, although I LOVE my iPhone, the battery life causes some problems for the executive on the go. As I travel from client to client, appointment to appointment, I am on the move and the last thing I need to go wrong is to loose touch with the world. Therefore, I depend on my iPhone to keep me in touch with work and my family.

I've been reading along on your series about the Find My iPhone [iTunes link] application and its slick remote security features [ed: start with How to use Find My iPhone on an iPad, then read How to Remote Lock your Apple iPhone] but for reasons I don't reall understand, when I signed in to my Mobile Me account to use the service, it listed a bunch of devices I no longer have. I want to clean the list up, but I just don't see how to do it on my iPhone??

I'm pretty sure that I lost my Apple iPhone 4, which is bumming me out, and while I already locked it remotely [see How do I remote lock my Apple iPhone?] I want to send a message to the person who might be trying to hack into it that I'll pay them a $20 reward, no questions asked, if they'll return it to me. Can I send an emergency text message to my iPhone?

I think my Apple iPhone was stolen, but I suppose it's possible I just forgot it somewhere. Problem is, I have lots of personal information on the phone and have skipped the hassle of having an access code in the interest of answering phone calls more quickly. Now I want to use the remote-lock capability to send the lock request to the phone, just in case someone does find it and starts playing. How can I easily do that?

This is just weird. In the last month or so my Apple iPhone has started beeping for an incoming text message multiple times if I don't indicate that I've read it, whereas before it just notified me once and was satisfied with that. Has something evil happened to my iPhone that everything's in triplicate now?

I just bought an iPhone 4 and am psyched about it, but I want to copy music from my iPod Nano onto it and am stuck. Is there a special cable or something I need? How do I copy music from an iPod onto an iPhone?

Alright Dave, come clean. I've seen you at a meetup playing a game on your iPhone 4, but I've never known what games you enjoy. I know from your Facebook updates that you're a pretty serious gamer, so what do you find appealing and worth playing?

I've been looking for a nice sounding clock radio that would let me dock and charge my iPods or iPhone 4, without having to break the bank. The Apple Store has some really nice ones, but at a premium price, like the terrific $399 Bose SoundDock that sounds great but requires a second mortgage.

Here's the funny thing about almost all of these iPod docks, however: they don't have clocks. Those were my two must-have items, actually. I wanted a clock so I could see the time at night, and I wanted a nice-sounding dock speaker system compatible with the range of iOS devices I own.

Enter the iHome iP90 Am/Fm clock radio for iPod and iPhone. With a street price as low as $70 (see Google Products for your options), it's not breaking the bank, but it has nice sound and a lot of thoughtful features that made me glad I had it on my dresser...

I'm borrowing my girlfriend's Chevy Equinox (don't tell her, but I actually like it better than my Ford F10) and want to be able to use my Apple iPhone as a hands-free cell phone in the car. It has a fancy navigational system that includes bluetooth but I haven't figured out all the steps necessary to pair the iPhone with the Equinox. Do you by any chance know how to do that, Dave?

How do I create menu folders [ed note: actually you're talking about app folders on your iPhone / iOS 4 home screen] on my iPhone 4?

I know how to add new apps to my iPhone, but I'm not entirely clear how I update those apps when there are new versions available. Is this something I can do on my phone, or do I need to use iTunes to update iPhone apps?

I am a pretty heavy user of my Apple iPhone 4's email capability, constantly reading messages as they arrive and sending out responses after tapping madly on the tiny virtual keyboard. It works. My question is whether there's a way for me to see my sent messages on the phone, so I can check prior discussions I might have had with an individual??
