A forum poster over at XDA-Developers has managed to lay his hands (at the cost of $900 (bargain!)) on the an AT&T branded HTC Touch Pro. The device, obviously intended for the US market, features 3G on the 850 band and also lacks the front facing VGA camera that denotes 3G phones in the European market. The TouchFlo3D interface also features some AT&T branding.
Of note is the unusual configuration of the keyboard. Despite being 5 rows, the number keys are still function keys, and the top row is occupied with punctuation keys.
There has been some speculation whether AT&T will carry this phone, since it seems HTC has been getting more support from CDMA carriers than AT&T recently, but this development is certainly very good news for US GSM customers.
