Nokia promo video inadvertently unveils Windows Phone Tango powered Lumia 900

In a video intended to outline its take on the Windows Phone platform for developers, Nokia has unveiled a future handset running Microsoft's OS, believed by most to be the Lumia 900.

The promo shows an as-of-yet unannounced device, slightly larger than the recently released Lumia 800, sporting a screen estimated to be around 4.3 inches.

Aces are high

The specs themselves appear similar to that of the rumoured-but-also-unconfirmed Nokia Ace, suggesting the two devices are potentially one and the same.

Commentators speculate both the Ace and unnamed device in the video are likely to feature an 8MP AutoFocus camera, as well as a 1.4Ghz single core processor.

Other talk, however, suggests a dual-core processor could be on the way, coinciding with the launch of Tango, the next update to Windows Phone.

Indeed, rumours are abound of a Q1 2012 release date, though Nokia is currently tight lipped on the whole issue.
