Sony Ericsson is no more, but that does not mean ghosts from the past cannot visit the present. It seems that previously unreleased photos of a prototype from Sony Ericsson was revealed, where this smartphone ran on the Windows Phone 7 operating system. Now, we all know that Sony Ericsson currently plays nice with Android and has not released nor announced a Windows Phone 7 device to date, but it seems as though they did have that intention to do so just last year. Just what led to the prototype’s demise? Seems to be a classic case of a meteor wiping out dinosaurs that roamed the earth a long time ago, don’t you think so?

There is a slide-out QWERTY keyboard that some might remember seeing in the Sony Ericsson Text Pro, where it sports instantly recognizable Sony Ericsson styling, while the camera is accompanied by an LED flash and is said to be able to record High Definition video. No idea on whether the prototype ran on Windows Phone Mango, or was it the older version, but it purportedly worked without encountering any bugs.
