HTC has unveiled two Windows Phone (Mango)-based smartphones, the HTC Titan and HTC Radar.

The HTC Titan offers a 4.7-inch display, HTC's largest phone screen to date, wrapped in an ultra-thin 9.9mm aluminum case, said HTC.

"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.

Both HTC Titan and HTC Radar include a dedicated hardware camera button which enables users to capture images without unlocking the phone while the f/2.2 aperture lens and back-illuminated sensor provide improved low-light performance, said HTC, adding that the devices can shoot HD (720p) videos.

The HTC Titan and HTC Radar will be broadly available from October 2011 globally, beginning in Europe and Asia, HTC said.
