Official Facebook app for Windows Phone 7 now available
The app has pretty much every feature you'd expect these days -- it lets you "post status updates, check your news feed, review your upcoming events, manage your inbox, upload photos, publish notes, accept friend requests, and look at your friends' photos, walls, and info".
The UI, in a similar fashion to most WP7 apps we've seen so far, makes good use of WP7's trademark 'Metro' UI and fonts. And yes, it's beautiful, as you can see from the screenshot to the right.
The application is now available in the Windows Phone 7 Marketplace (that's accessible on your PC from the Zune software).
