Microsoft(s msft) continues to refine the Facebook(s fb) experience on Windows Phone with both a standard and beta version of the social networking app available. The latest beta software, version 5.3, adds a key function previously missing: Video uploads. Windows Phone 8 or 8.1 handset owners can download the beta to test video uploads -- you can still keep the generally available version too -- while also gaining better app performance and design improvements Microsoft has added. The app is looking better all the time, although it certainly has a different design when compared to other platforms; not necessarily a bad thing if you like the look of Windows apps.
