It's a regular occurence - prior to a major phone launch, manufacturers (and/or carriers) will often hold launch parties promoting the product. To that end, T-Mobile USA is sending out invitations to an HD2 launch party on March 16th in New York City. The date of the party lends major credence to the rumored March 24th retail launch date as well. The company had alluded to a March launch in prior statements anyway, so the timing of everything makes sense.
With the device (presumably) so close to the retail shelves, will you splurge and pick one up? Sound off in the comments!
