If you're looking out for the HTC HD2 from T-Mobile, then mark March 24 on your calendars. After all, this Windows Mobile 6.5 smartphone is touted to roll out on that date, where it will reportedly retail for $199 on a two-year contract, whereas others who prefer to take the unlocked route will have to fork out $449 initially. Be wary of this though if you want to make the jump to Windows Phone 7 straight since HTC has confirmed that this will be incompatible for future upgrades.
