Is Sony Ericsson working on a second Windows Mobile smartphone?  If an image posted at Mobilewhack turns out to be genuine, the answer is maybe.  The image shows the W1, a Walkman-branded smartphone with a large screen, a navpad, and a Windows Mobile 6 Pro screenshot.  The image also lists select features of the device, which include a 6.1MP camera, a VGA screen and 32GB of onboard flash storage.

Sony Ericsson is already prepping its first Windows Mobile device, the XPERIA X1, for release as early as September, so a second WinMo handheld isn’t outside the realm of possibility.  The image is labeled as a concept, however, which could mean that it’s nothing more than the offspring of a boring afternoon and a passing knowledge of Photoshop. 

Rumor or reality, we’ll keep you posted.
