I just called Apple store this morning and they said I have to activate the iphone in their store with AT&T if I have to buy one. Same as AT&T store. Is that means the only way that I can buy one and unlocked on ....."EBAY"? I'm currently using T-mobile.
Both previous answers are incorrect. To purchase the 3G iPhone, you have to activate it in the store and sign a 2 year contract before you can leave with it. The 1st gen iPhone was activated at home through iTunes. This new version is not. It HAS to be activated in the store. Apple and AT&T do not want this phone unlocked and "jailbroken" and are taking steps to ensure it cannot be. Sorry...you will not find a 3G iPhone on eBay.
nope. u could just get the phone and activate it a t your house and then u could activate it or unlock it whatever u wish for..but apple canotforce u to activate it at their store it has to be done by urself..
