It's really the 3G frequencies that are different b/w ATT and T-mob. The reason the t-mob N1 can't get 3g on ATT is b/c it doesn't support the proper frequences, which are 850mhz and 1900mhz if i'm not mistaken.

Actually China and Taiwan use CDMA heavily still. And no ATT and TMO do use dif freq for 3g. Att is 850 and 1900 as you stated and TMO is 900/1700/2100. TMO matches what most other countries in the world use for 3G. ATT and Rogers are the only ones using the 850/1900.
