Another WP7 Phone Arrives On AT&T
Other than that the rest of the phones innards remainly largely the same, with a 1GHz Snapdragon processor, 5-megapixel camera, and built-in kickstand. The HD7S will ship with the NoDo Windows Phone 7 update which includes copy-and-paste capabilities and performance enhancements, so if you were hoping for a WP7 device that ran on Mango it seems like you will have to wait a little longer.
