We've been throwing around a March launch date for the T-Mobile HD2 for a while now. And if this slide, purportedly from an internal T-Mobile presentation, is correct, it seems we're on the money. It shows the HD2 being released on March 24, along with a slew of other current and future devices. Not much to say other than that, until we see it confirmed by other sources. [PPC Geeks via TMoNews]
