We’ve seen a few Window Phone 7 devices leaked lately. While the Asus handheld and the previously leaked HTC smartphone have their own peculiarities, these latest leaked images of HTC's AT&T-bound Windows Phone 7 device is beyond anything we’ve seen thus far. Known only as the HTC T8788 for now, the device has a surprise for us in its design. The body of the device slides open in landscape mode, revealing not the keyboard as expected, but a large speaker instead. Now, are we in for a crazy WP7 music enable smartphone or something? Check out another image after the jump.
