The HTC One Android smartphone is now available for purchase through all channels at Sprint, AT&T and online at T-Mobile. Sprint and AT&T are each selling the 32GB model for $199.99 with a new or renewing two-year contract. For a limited time, Sprint is offering an additional $100 discount for any customers willing to switch from another operator. AT&T, of course, has exclusivity and bragging rights on the 64GB model at a price-point of $299.99, also with an agreement. T-Mobile’s HTC One costs $99 down plus $20.00 monthly payments for 24 months – or you can pay in full at $579.99. It seems silver is the only available color on all three carriers at the moment, though the black option should arrive soon enough.
