Vibrant 4G FCC tag

While we can never be 100 percent sure with these things, what looks like the Samsung Vibrant 4G has just passed through the FCC, ready to hit T-Mobile store shelves soon.  We can be sure it's a Samsung phone, with the correct radio to work on T-Mobile's 3G and 4G networks, so all signs point to it being the Vibrant 4G that we've been talking about for the past week.  With Mobile World Congress coming up soon, and Samsung set to make a big announcement, even I can put a few pieces together.  If all the rumors and leaks are true, we could be seeing it come Feb. 23.  [FCC via Engadget]
