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 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. It delivers advanced phone features including GPS functionality with access to turn-by-turn navigation from TeleNav GPS Navigator, 16 GB of internal memory, a 5 megapixel autofocus camera with dual LED flash, and HD 720p video recording. Other features include Wireless-N Wi-Fi networking, Bluetooth for hands-free devices and stereo music streaming, and a 1230 mAh battery for extended use while on the go.

Enabled for T-Mobile’s high-speed 3G network, the HTC HD7 offers fast data delivery and an enhanced Web-browsing experience that lets you connect quickly to social networking sites. And the 3G-enabled HTC HD7 will benefit from the enhanced speeds of T-Mobile’s upgraded HSPA+ network, which is being rolled out nationwide to reach up to 200 million people by the end of the year and offers speeds close to 4G connectivity.
