Another Windows Phone 7 device developed by HTC has been leaked out. Engadged gets the credit for bringing this leak online and says this device is targeted for AT&T customers in US.

The large screen doesn’t slide to reveal a keyboard but it’s a slide out speaker with kickstand. So far, device is called T8788. Of course this doesn’t match with the naming convention of HTC so expect a change in name before release.

No specs known yet, but phone seems to full of multimedia fun.
