Hi. I'm a current ATT Wireless customer, with a Motorola phone. My contract is over - I am still paying the same as when my contract was in force, and I'd like to try an iPhone. But, I don't want a 2 year commitment to ATT. My understanding is that I can but an Iphone (I want a 16mb 3G phone) on ebay, and walk in to an ATT store, and have them activate it with my old ATT phone number. Will they really do this? Will they really do it without forcing me into a contract? I'd like to be certain before I buy the phone. What if I buy a phone that is unlocked and/or jailbroken - will they re-lock the phone, or refuse to activate it? Thanks. p.s. i'm sure this question has been asked and answered , but i did a search, and checked the faq, and didn't see anything.
