T-Mobile announced yesterday that it would be carrying the HTC HD2 on the network. The bad news is that the phone will not be upgradeable to Windows Phone 7. Therefore, the phone will be outdated by the holiday season. The HTC HD2 has a 4.3-inch capacitive touch display that really shines. With a 1GHz Snapdragon processor, the HD2 will be snappier than most other Windows Mobile phones currently out there on the market. The phone will be available on March 24th for $449.99 on a Even More Plus plan, or $199.99 with a two-year contract.
