The Windows Phone 7.8 update for old WP devices is set to arrive in early 2013 but a video has already surfaced showing the update running on the Nokia Lumia 900.
The title of the video is “WP 7.8 update for Lumia 900 – quick preview“, and by quick preview it meant 37 seconds of hands-on. It doesn’t show much detail but you’ll notice resizable live tiles, a new Xbox icon, and a fluid UI navigation.
Expected WP 7.8 features include a new boot, lock and home screens, more color themes, Bluetooth file sharing, IE improvements, Xbox Smart Glass, and lots of OS fixes. The WP 7.8 OS on the Lumia 900 is not the final version so expect some things to change until its official launch.
