    Nope. It will never happen. T-Mobile uses a different 3G frequency than the rest of the North American GSM standards... EDGE is the best you're gonna get.

    Because it's looking for a 3G signal, which it will never find on T-Mobile... and I bet your battery drains rather quickly... trust me, there is no 3G service for the GSM iPhone on T-Mobile.

    AT&T and the other North American GSM carriers (except T-Mobile) use 850 (sometimes referred to as 800) and 1900 mHz ... T-Mobile uses 1700 and 2100 mHz. The iPhone is set to the AT&T frequencies...

    EDIT: BTW, lower case is the GSM method of indicating NO connection has been established. That holds for GPRS (gprs), EDGE (edge) and 3G (3g).

    Hank is right. Using an AT&T iPhone on T-Mo will only get you Edge, no 3G.

    Yup no 3G unless apple starts making phones for tmobile but since you have a iPhone on tmobile that's a accomplishment all by itself
