Aaron unboxes AT&T's HTC HD7S, the newest Windows Phone on the nation's second largest wireless carrier.  Sporting a 1 GHz Snapdragon processor, 4.3-inch display, 5-megapixel camera, and a kickstand for easy viewing of media, you may think it's identical to T-Mobile's HD7, but the main difference outside of the HD7S' yellow color scheme and preinstalled AT&T apps is that the display is a Super LCD.  As you would expect, the display quality is much improved, and it's a welcome addition to AT&T's already diverse Windows Phone lineup.
