Update: Another picture has surfaced over at IT168, and this time the Xperia duo name is quite clear underneath.
A mysterious device that most are pegging as the upcoming Sony Xperia Duo has made a cameo over at Chinese website IT168. Rumor has it the the Duo moniker suggests that this will be the first dual-core device from Sony, but we have nothing that confirms (or denies) that info, so take it at face value.
Very little is known about this device at the time - the pictures suggest a near edge-to-edge display and a possible front facing camera, but that's about it. Have a look for yourself:
Anything else that could be said about this device would be pure speculation, so I'll let you decide for yourself what you think is going on here.
