Nokia Champagne handset spotted on Windows Phone app, dancing the Tango?

Has a Windows Phone app just popped the cork on a new Nokia handset? It very well may have, based on the above image. Extracted from the "I'm a WP7" app and first identified by the folks over at WP Central, this screenshot purports to reveal a Nokia device codenamed "Champagne" -- a rather delectable moniker that, until now, wasn't even on our radar. At this point, little else is known about this mystery phone, though according to WP Central, it's running Windows Phone 7.10.8711 -- suggesting, perhaps, the presence of Tango, the Mango successor for low-end devices. Could this be a mythical, LTE-equipped Lumia 900 / Ace handset for Verizon Wireless? Could we see it at this year's CES? Only time will tell, but we'll let you know as soon as we hear more.
