As expected, T-Mobile has announced the HTC HD2, arguably the most impressive Windows phone out there to date. Clocking in at a 4” screen, 1 Ghz processor, 5 megapixel camera, and (comparatively) snazzy TouchFLO user interface on top of Windows Mobile 6.5, the HD2 is a handset many North Americans have been waiting for. Take a look at our hands-on video review to see just what all the fuss is about. Those hankering to get started with this bad boy will have to wait until the spring. In the meantime, you can stay up-to-date on T-Mobile’s HD2 availability over here.
