T-mobile 3G does support 2100 mhz. From their website: “What frequency does your 3G network support?
Our 3G network supports both the 1700MHz and 2100MHz frequencies”.
So a smartphone like the Nokia E71-3 which uses 3G freqs of 850 and 2100 should work on both AT&T and T-mobile

T-Mobile does not use 2100mhz for 3G. 2100Mhz is the international 3G standard. We just like screwing things up in the US. That is why non-US 3G phones dont work on 3G here.

Yeah AT&T runs 3G on the 850 & 1900 frequency bands while T-Mobile runs 3G on the 1700mhz frequency band

AT&T uses a different frequency for 3G compared to T-Mobile. The AT&T version of the Bold does not have that frequency so it will not work for 3G. You will still get EDGE and phone calls but 3G is out the door until the T-Mobile specific one comes out.
