Xperia X1, which includes 3-inch clear wide VGA display and a full QWERTY keyboard within a quality metal-finish body, is an arc slider phone built to address the customers who need a premium, converged mobile experience.

“Our vision for the XPERIA X1 is to deliver a seamless blend of mobile Web communication and multimedia entertainment within a distinctive design,” said Rikko Sakaguchi, Head of Portfolio and Propositions, Sony Ericsson.

The phone has quad-band GSM (850/900/1800/1900MHz) and 4 bands of HSDPA/HSUPA (850/1700/1900/2100MHz or 900/1700/1900/2100MHz) support. It includes also WiFi connectivity and a 3.2 megapixel camera with auto-focus. Xperia X1 measures 110mm x 53mm x 17mm (4.3" x 2.1" x .7") and weighs in at 145g (5.1oz) and it includes also GPS support.

For those customers who do not like the touchscreen phones, Sony Ericsson Xperia X1 offers a stylus and handwriting recognition. The phone, which will be delivered in two colors, Solid Black and Steel Silver, is scheduled to be available in the second half of 2008.

Building a mobile phone with Windows Mobile is quite a premiere for Sony Ericsson. So far, the company sold more than 100 million handsets in 2007 and excelled in sales of imaging and music-enabled devices, such as Cyber-shot and Walkman phones, has used the Symbian operating system for its smartphones.
