The HTC Sensation is described as a “multimedia superphone” by the company. It comes with a 4.3”widescreen qHD display, hi-fi audio instant capture camera, a “richer Internet experience” (multi-window browsing, quick lookup tool, Flash support), and an active lockscreen.

The locksreen will show things like portfolio information, friends’ status updates, etc.

The device will be available this summer in the U.S. for T-Mobile.

“Consumers have quickly transformed smartphones into consumer lifestyle hubs that are pocket-sized entertainment centers that enable people to take their favorite multimedia content with them wherever they go. The new HTC Watch service makes it fun and easy for people to access premium movies and TV shows while on the go,” said Peter Chou, CEO of HTC Corporation. “The HTC Sensation 4G combines this great multimedia experience within the latest HTC Sense experience in a premium device that delivers a powerful and unprecedented smartphone to our customers.”

“The HTC Sensation 4G delivers the ultimate in speed and entertainment on America’s Largest 4G network,” said Andrew Sherrard, SVP of marketing for T-Mobile USA. “With a lightning-fast dual core processor and 4G speeds, customers will experience the difference when accessing rich media and content on the HTC Sensation 4G’s beautiful qHD display. We look forward to adding the HTC Sensation 4G to our industry-leading lineup of 4G smartphones.”

If you’re still worrying about iPhone availability for T-Mobile, this device would reflect T-Mobile’s initial statement about that: “T-Mobile USA remains an independent company. The acquisition is expected to be completed in approximately 12 months. We do not offer the iPhone. We offer cutting edge devices…”

The HTC Sensation has a unibody aluminium construction and contoured glass along the entire edge of the screen, which HTC says protects your screen from grit when it’s face down.

It has a 1.2 GHz dual core processor, and runs Android Gingerbread (2.3) with Sense 3.0.
