A friend of mine has a 3Gs and she wants to have it on t-mobile but with 3G is this possible? if it is, can someone help me out here and explain on how to do this? Thanks, in advance
The frequency on the 3G and 3GS is different from the high speed frequency T-Mobile uses. You can use the phone if it has been unlocked, but it will be limited to EDGE data speeds.
