Taiwanese smartphone and tablet maker HTC has unveiled its new HTC TITAN and HTC Radar Windows Phone-powered smartphones.

The HTC TITAN boasts the company’s largest screen to date - a 4.7" super LCD (480 x 800) display, while the device is encased in an 9.9 mm brushed aluminum case. This Windows Phone (Mango) based device is powered by a 1.5 GHz single-core CPU and also sports an 8 MP rear-facing camera and 1.3 MP front-facing camera for live video calling.

Also running on Windows Phone is the HTC Radar, featuring an elegant aluminium unibody design (although coming in at a millimeter thicker than the TITAN) and a 3.8" super LCD touch-screen boasting a WVGA (480 x 800) resolution. It is powered by a 1 GHz processor and sports a 5 MP rear-facing camera as well as a VGA front-facing camera, 512 MB RAM and 8 GB of internal memory.

Following the announcement of these new devices Microsoft’s corporate vice president and director of Windows Phone Program Management, Joe Belfiore, confirmed that the Mango update will enable support for front-facing cameras.

Both phones can record HD-Ready (720p) videos and include HTC Watch, which is an application and service that provides users with a library of the latest movies as well as TV series, and also feature virtual 5.1 surround sound for a enhanced audio experience.

HTC’s TITAN and Radar smartphones will be broadly available around the globe as of October 2011, beginning in Europe and Asia. No local release info is available yet.

“The new HTC TITAN and HTC Radar smartphones raise the bar with new advanced photography, multimedia and social capabilities that enable you to take full advantage of the latest Windows Phone innovations,” said Jason Mackenzie, president of global sales and marketing, HTC Corporation.

“With its large, cinematic display, the HTC TITAN packs an amazing amount of power and innovation into a device that is unlike anything you’ve ever held before and the HTC Radar’s aluminum uni-body, compact size and finish will capture people’s attention,” Mackenzie continued.

In related news HTC also announced a strategic partnership and investment with Beats Electronics last month, which is audio company founded by legendary hip hop producer Dr. Dre and chairman of Interscope Geffen A&M Records Jimmy Iovine in 2006.
