How about an XPERIA handset with Windows Phone 7 on board? Ahmed Adel Hossny Rizk created such a device and named it XPERIA X7. The smartphone is pictured below and its creator mentions that it comes with a 3.2 inch AMOLED touchscreen, a 10 megapixel camera and Windows Phone 7 for an OS. What do you think?
