During a high-profile presentation at this year's CTIA Wireless conference in Las Vegas on Tuesday, Sprint Nextel CEO Dan Hesse unveiled the company's 4G smartphone - the HTC Evo 4G, which will support the carrier's WiMax high-speed wireless service.

The new phone, manufactured by HTC Corp, features a 4.3-inch capacitive screen, which is not only 30 percent larger than the Apple iPhone's screen, but has also been designed to enhance the users' video viewing and Web browsing experience; thereby taking multimedia to "a whole new level," as Hesse put it.

In addition, the smartphone, which will run on Google Android 2.1 operating system, boasts a 1GHz Snapdragon processor; and two cameras - an 8-megapixel camera, with auto-focus and an HD-capable camcorder, for shooting photos and video, and a 1.3-megapixel front-facing camera for offering support to video chat and other similar applications.

Calling the Evo 4G "the world's first fully integrated 4G consumer handset," Peter Chou, the HTC chief executive, elaborated that the device has been under development by HTC and Sprint, in collaboration with Google, since May 2008.

Chou further added that the Evo 4G, which will likely be released in summer this year, "gives a clear indicator of how mobile broadband experience is starting to move beyond the fixed-line broadband experience by what it offers in terms of local and personal relevance."
