AT&T/iPhone: I bought an iPhone 4 on craigslist. I plan to cut down my 3G's sim into a micro-sim and put it in the 4. However, before I got started I factory reset the 4 and now it wants to go through an activation process. What does "activation" mean, in this context? [more inside]

I don't want any access to email when I am on vacation this year. However, I do need cellphone access. I am currently using an AT&T iPhone 4. Can use the iPhone 4 micro sim card (with an adapter) in a GoPhone? Barring that, what is the most featureless AT&T phone I can put my iPhone 4 sim in (including ones I can buy used). Thanks!

My wife wants to get an iPhone, and is currently on Verizon. I already have one. What's the best route for us to go? If she gets an iPhone4, can I take it and give her the 3GS just by swapping the SIM cards? What is your experience with AT&Ts family plans, or are we better off having separate accts? Does ordering the phone online make anything more difficult? [more inside]

Two iPhones, a 2G and a 3G, on a family plan. Adding a third, a 3GS. Can I just swap the SIM cards to get the phone numbers onto the devices I want them on, or does AT&T need to get involved? [more inside]
