I just upgraded from MobileMe to iCloud and I don't see much different, except my iCal calendar is now empty! This is a huge problem as I use it to schedule patients and, well, it's made me rather anxious. Help!!

I've been on MobileMe for years now, and love that it could automatically sync calendars on my iPhone, iPad and computers, even to where I could access my calendar (and contacts, lest I forget) from any Web browser in the world. Very handy for someone who lives and dies by his calendar. Now there's a new player in town, iCloud, and it's a mandatory upgrade for all MobileMe users.

How can you most easily upgrade your MobileMe account to iCloud?

I have both an SMTP and a MobileMe account set up on my iPhone and just noticed that when I send email from the phone, it has a MobileMe return address, not my proper account address. I think it's picking the wrong account, not just wrong email, so is there a way to change the iPhone default email account?

I'm enamored of MobileMe, the data sharing and sync service from Apple, but $99/year seems pretty steep. Is there a cheaper way that I can renew my MobileMe membership and save a few dollars?

Got a new Apple iPad and since you're already a MobileMe subscriber, you're dreaming of having it just magically get all your calendar events, contacts and even Safari bookmarks? Of course you are! The question is, how do you hook up your iPad to your existing MobileMe service?

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?

I really like how iPhoto works with my Apple MobileMe account on the Web and the gallery it produces is very cool. My friends, in particular, really tell me they think it looks cool and makes it fun for them to see the photos I upload. Problem is, sometimes I want to create password-protected private albums, not just have everything I upload available to the general public at large. How do I do that in iPhoto?
