What you see before you here is the FCC label for the HTC EVO 3D. The EVO 3D that ZOMG has a T-Mobile 3G radio inside!
Gets you going, doesn't it? There are a couple of possibilities here: One is that, sure enough, it's coming to T-Mobile in the United States. But the other, more likely scenario is that it'll hit something like Wind Mobile or Mobilicity in Canada, which, in addition to being a GSM carrier, also rolls with the 1700MHz.
It's nice to get excited about these things, folks. But let's not put the cart before the horse.
