Windows Phone looks set to welcome Sony into the Microsoft fold, if a bunch of leaked spy shots of a WP7-toting Sony Ericsson are anything to go by.
With Sony and Ericsson having already publicly parted ways, the old branding suggests the leaked images are pretty old. But it could still be part of Sony's plan to put itself on the smartphone map now it's going it alone.
While Sony Ericsson has never officially confirmed plans to enter a partnership with Microsoft, the company hasn't ruled it out either, despite focusing its efforts on its army of Android phones.
If one is on the cards, we'll no doubt hear about it at Mobile World Congress.
