If the rather binary choices of blue and white for the current model of the T-Mobile's variant of the Samsung Galaxy S III don't appeal, there's another option available. A Titanium Grey color has popped up on Best Buy's website, at the same subsidized price as the other T-Mobile models, currently $179.99 with a two-year contract and a whopping $700 outright. Just be aware that if you actually buy a T-Mobile Galaxy S III at any time in the next month, your future self may come back Biff Tannen-style and smack you for being so shortsighted.
That's because T-Mobile is finally ready to start rolling out its LTE network, like the rest of the major American carriers, with a launch coming as soon as this month. According to a statement from T-Mobile's Chief Technology Officer Neville Ray just yesterday, a refreshed Galaxy S III sporting an LTE radio will be the first phone to take advantage of the new, speedier network. (T-Mobile's Galaxy Note II will also get a software update to work with LTE bands, just in case owners of the original T-Mobile Note didn't have enough buyer's remorse already.) Even conservative estimates place T-Mobile's LTE rollout in the second quarter of this year.
So in conclusion, Best Buy's got a spiffy new color of the Samsung Galaxy S III for T-Mobile, and if you buy it now, it's quite possible that you will regret it for the rest of your life. Or at least until the end of your upgrade cycle.
