Like puzzles? Then you should head over to a new teaser site posted by T-Mobile, and try to guess the name of a new handset that's coming to the carrier in just a couple of days. The page shows portions of a pictogram puzzle, and a countdown to the official announcement. Though the bottom portion of the puzzle is mostly covered up (for now), the top line is pretty easy to figure out. We won't take the fun out of it for you, but let's just say it might have something to do with this event.
Update: Well, it looks like T-Mobile has let the cat out of the bag via its Twitter account. The new smartphone will be the Samsung Vibrant, which will feature Samsung's 1GHz Hummingbird processor, a 4-inch touch screen, and a 5-megapixel camera. Like the Samsung Captivate for AT&T, the Vibrant is part of the company's Galaxy S series.
Release date and pricing information were not announced at this time, but we expect to see the smartphone at the launch event June 29, so check back for hands-on impressions, photos, and video.
