Fresh out of a development factory in China, is a video of Nokia's 'leaked' Sea Ray Windows Phone running Mango. In the video, you can see the Nokia N9 lookalike, sporting physical buttons laying rest to the rumors about their absence in favor of virtual buttons.
Also making an appearance is the new '7' logo screen and lock screen, but a front-facing camera seems to be missing. There's also word that the handset in this video is running a Mango RTM build, specifically 7710. Check out the video below :
