Facebook for Windows Phone makes it easy to stay connected and share information with friends. You can post status updates, receive Live Tile updates, check your news feed, review upcoming events, check in to places, manage your inbox, upload photos, publish notes, accept friend requests, pin Places and Messages as Tiles, and look at your friends’ photos, walls and info.

And don’t forget about Facebook Chat – it’s built into the Messaging app on your Windows Phone.

New for WP8: Improved performance, support for multiple resolutions and tile sizes plus more!

Of course, as any Facebook user knows, Facebook will never be "out of beta".
