Bellevue, Wash. — Feb. 19, 2013

T-Mobile is excited to partner with HTC to bring our customers the new HTC One®, a T-Mobile 4G LTE smartphone. The new HTC One introduces HTC BlinkFeed™, HTC Zoe™ and HTC BoomSound™, key HTC Sense® innovations that reinvent the mobile experience.

The new HTC One is T-Mobile’s first Android smartphone featuring the new HTC Sense experience with HTC BlinkFeed at its center. HTC BlinkFeed transforms the home screen into a single live stream of personally relevant information such as social updates, news and photos giving people fresh content at a glance without the need to switch between applications. Wrapped in a zero-gap aluminum unibody, the brilliant 4.7-inch full 1080p HD screen is the perfect display for the new breakthrough camera experience of HTC Ultrapixel Camera with Zoe which gives people the ability to shoot high-res photos that come to life in three-second snippets.

When combined with T-Mobile’s industry-first Unlimited Nationwide 4G Data plan with no annual contract, the new HTC One provides amazing 4G experiences at a superior value – without limitations – that only T-Mobile can deliver. Information about the HTC One can be found at T-Mobile.com. Additional details, including device availability and pricing, will be shared at a later date.
