T-Mobile's new 3G network uses UMTS/HSDPA 1700MHz. AT&T uses UMTS/HSDPA 850MHz/1900MHz. U.S. GSM version of the Diamond supports 850/1900MHz, so you can only use your phone on AT&T for 3G services.
If you're looking for a WM6 phone to use on T-Mobile's 3G network, Sony Ericsson is coming out with a U.S. version of their Xperia X1 that will work on both T-Mobile and AT&T's 3G networks. Looks like a nice phone. More info here:
