So I finally made the switch, after my 1 year contract at T-mobile expired, and I can now retire my 1st gen iPhone. AT&T.... I like the service so far, and I am loving my new iPhone 3G. The speed is awesome! It is going to take me a while to get used to this ugly dull "yellowish" screen. Everyone tells me it's suppposed to be more "natural" but I am so used to the bluish screen of the 1st iPhone that this screen really looks nasty. Anyways, what do I need to do to get my sister, who currently uses Tmobile, working on this iPhone?? It has been pwned and jailbroken with pwnage tool 2.0 and has the latest iPhone firmare. Do I need to reset the phone? Can I just give the phone to her and have her stick her sim card into the phone and expect everything to work? Does she have to get a data plan to use the internet? help! thanks. She is very very excited to get this phone!
