I have had t-mobile for almost 2 years now and live in an apartment 10 miles north of downtown Atlanta that gets spotty signal in terms of AT&T. I know this because my girlfriend has an iphone from a few months ago and it would get between 3 bars in some places to 0-1 in others in my apt. I really want the iPhone and so I will KEEP my t-mobile service in tact with my old phone and create a new AT&T account (obviously not porting over the number right now) and have 2 phones tomorrow. The idea is I will test out how well the reception in my apartment is with the iPhone for a week or 2 and see how it is, and if it works well enough I will go back to AT&T to port the t-mobile number over. If it sucks and is spotty I will return the iPhone and pay the restocking fee......Anyone else doing this?
