If you liked the look of Samsung's Galaxy Tab 2 10.1 when we reviewed it back in May, but were holding out for a T-Mobile 4G variety, then your patience might soon be rewarded. A Tablet-shaped device from Samsung sporting the model number SGH-T779 has just popped up at the FCC. While that code name might not tell us much, the T-Mobile branding, and the 4G logo are a little easier to make sense of. There was another model, SGH-I497, that went through the FCC with the same ID -- which had a distinct AT&T / Galaxy Tab 2 10.1 flavor to it -- so betting fans might consider the odds of this being the same thing, but for another operator, as being reasonable. Those who prefer not to chance the hand of fate, likely only need wait a short while, however, for this to pop up on the network's store to find out.
