Just one week after we got a sneak peek at Windows Phone 7.8 running on a Nokia Lumia 510, a new video has surfaced showing the update running on a piece of hardware that many of you will be more familiar with. This new clip features an international Nokia Lumia 900 running Windows Phone 7.8, and while there's nothing new shown off in the video, we do get a look at how the resizable live tiles found in the 7.8 update look on a cyan 900. 

Windows Phone 7.8 will bring some of the new features found in Windows Phone 8 to existing Windows Phone 7.5 handsets, including the aforementioned resizable live tiles, a new Start screen, an increased number of accent colors and the ability to display the Bing Picture of the Day on a device's lock screen. Microsoft recently shed a bit more light on when the update is expected to roll out to users, saying that it's undergoing testing from both Microsoft and its partners and that a roll out is expected to begin in early 2013. A quick preview of what users can expect from that update is embedded below.
