Considering that the iPhone 4 uses a Micro-SIM and all of us using prior iPhones have full SIM cards, we're not going to be able to just pop them into the phone, plug the phone into iTunes and have it automatically activate (on our accounts). So how do we do that then? I have a FAN account that I'd most definitely NOT want tampered with in any way and I just thought about this possible problem. Could anyone alleviate my concern? Thanks.
