Yesterday we brought you some in depth information of what will be coming in the Windows Phone 7.8 update, expected to appear in China in a few weeks (presumably with the launch of the Nokia Lumia 510).  New features such as a revamped Tile design, new Tile sizes and dynamic Lockscreen wallpaper (Bing) were revealed including the current build number.

Now a new video, presumably from Winp.cn, shows the current build of Windows Phone 7.8 (8858) in action. Actually, it’s less action and more of a nice, soothing stroll on some of the more superficial changes coming in the OS update. The new tiles are shown off and we even see the Bing lockscreen wallpaper working (we’re hoping that third-party apps can take advantage of it too like in Windows Phone 8).

Overall, it’s nothing groundbreaking but it does backup what we revealed yesterday. Here the OS is in Chinese, so it may be hard to discern some of the items in Settings but the features should be obvious. Speaking of, we’re guessing that the CPU on board is only a 1GHz or so judging by the OS performance, though some of the exact and final specifications need to be confirmed yet for this device.

The Nokia Lumia 510 is expected to be for Asian markets, specifically China. It’s a low-cost handset with a 480x800 4” LCD display, 5MP camera (no front facing) and just 256MB of RAM with a 1300mAh battery. Release date is expected before the end of the year.
