Sony Ericsson will unveil its first Windows Mobile based handset at the Mobile World Congress (MWC) in Barcelona.
The Sony Ericsson Xpreria X1 will not be available until H2 2008 and marks another Microsoft's win as it managed to get onboard with everyone except Nokia.
ITPro describes the Xperia X1 as an arc slider phone with a 3-inch VGA (800x480 pixels) touch screen, 400MB of internal memory with microSD card support, FM radio, a 3.2megapixel camera and a QWERTY keyboard, complete with Wireless LAN, HSDPA/HSUPA high speed connectivity - meaning that speeds of 3.6mbit will be achievable - as well as GPS.
The company will position the phone above the existing Walkman and Cybershot range and will compete directly with Apple's iPhone. Sony Ericsson had been missing a corporate, more upmarket phone in its range and the X1 nicely fills that gap.
Sony Ericsson is a partner on the Symbian Platform which owns more than 70 percent of the Smartphone market and it is unlikely though that Sony jumps ship altogether to Microsoft.
The company has also announced a number of other phones including several touch screen models.
