Welcome to the forum applelvr. I'm not quite sure and will have to done some searching. I haven't seen any other reports of someone using the iPhone 4 on T-Mobile.
The iPhone can only be used on T-Mobile as a 2g phone. T-Mobiles's 3g frequency is different than AT&T and the European frequencies for 3g. This cannot be adjusted.

Alex,
The iphone 3g and 3gs can be used on T mobile and they are on the same frequency as Att. I have the 3gs unlocked and its on Tmobile's 3g network.
