AT&T returned to supporting Microsoft in force today with three new Windows Phone 7 devices. The group is led by the HTC Surround, a unique touch-only phone with an emphasis on audio. A slide-out speaker gives it support for Dolby Mobile and SRS surround that improves the sound for watching movies from the Zune store or 720p video captured from the phone itself. A 3.8-inch touchscreen and a built-in Evo 4G-style kickstand embrace the idea of movie playback.
