We love our lock screens so much we have a dedicated wallpapers section for lock screens and now with Windows Phone 8 you can add custom live screens to your lock screen, this allows you to see much more meaningful info on the lock screen like weather, news and now even your Facebook photos !! With the latest update the Facebook app ( version 4.1 – thanks for picking up the error Steve ) on windows phone brings the awesome feature of using your Facebook photos as your phone lock screen background image.
So now you can select any album ( not individual images ) from your Facebook account and set it as Lockscreen image. The latest update also brings some performance improvement to Windows Phone 8 along with support for multiple resolutions and tile sizes.
Facebook is a FREE app for Windows Phone
