We knew good and well that HTC's One would be arriving on T-Mobile USA at some point, and for those uninterested in tying themselves to Sprint or AT&T, here's some news that matters: Best Buy has just confirmed to us that it'll begin shipping T-Mobile's flavor of the aforementioned phone on April 19th. The "Glacier Silver" kit will be on sale for as little at $249.99 on a two-year deal, whereas you'll be forced to pay $699.99 for the blessing of having no strings attached. Granted, T-Mob's Simple Choice suggests that no contracts will be involved, but if you take the bait on the subsidized price, you'll either be hanging with the carrier long enough to pay it off, or you'll be forking out the difference on the way to some other operator.
