Photos of HTC T8788 for AT&T show a slide-out speaker

AT&T keeps a diverse eco-system of OSes and it's getting ready for Windows Phone 7 to join the party. The WP7 powered HTC T8788, which is bound for AT&T, was photographed sliding open to reveal a surprise.

The HTC T8788 will inevitably receive a more memorable name but it's got a feature that will make it even more memorable. It's a side-slider, so you'd expect a QWERTY keyboard to pop up when you slide it out.

So, what does the lower half of the slider hide? A speaker - so the HTC T8788 should be one serious multimedia phone. It has a kickstand on the back too.
