HTC HD7 Windows Phone

One of the world's first smartphones using the Windows Phone 7 operating system, the HTC HD7 for T-Mobile pairs rich mobile multimedia features with a 4.3-inch touch display--the largest screen available on a Windows Phone 7 handset in the U.S. Its size not only gives you an extra-large virtual keyboard, but also allows you to enjoy your favorite videos and movies in cinematic style. It's also powered by a blazing-fast Qualcomm 1 GHz Snapdragon processor for a fast mobile data experience.
