It's my understanding that BB made the ATT 9700 to work one one set of 3G frequencies and the other to work on Tmobiles frequencies.

The unbranded is most likely ATT's frequencies. The blackberry website specifies that they are manufactured with two seperate frequencies.

FOR ME: ATT lets me roam on EDGE when Tmobile towers are not available but I only get full 3G when on Tmobile towers (I assume the frequencies again).

T-mobile is the best at allowing people to use their own phones. Call their tech support. They really are cool about it. They will even help you with using an Iphone on their network.

Call them.
