Sony Ericsson apparently isn’t interested in Windows Phone 7. I don’t blame them, why would they promote XBL in any way? But we are aware of some prototypes that were in testing running Windows Phone OS and a few bloggers found some prooftoo of the black model in existence. The prototype was supposedly code named Julie. The device looked pretty decent. With a slide out landscape keyboard, this could have given a tough competition to both HTC and Dell.
A white model of the prototype codenamed Julia was recently spotted by a forum.
Obviously, the plan to convert a prototype to commercial device didn’t work out so well. Sony Erricsson is doing pretty well with Android and I don’t see them making a device running Windows phone OS in future.
