If you’re a big Facebook user, you’ll notice the nice integration within Windows Phone. It’s not even necessary to install any other app. After entering your account login at the settings menu, you’ll be able to update status, check-in, post to friends’ walls, check friends’ updates, share photos, view albums, and start a chat. I shot a video to show you how it works on the Nokia Lumia 800.

My favorite is the chat integration on the Nokia Lumia 800. On the Galaxy Nexus or the iPhone 4S, you’ll need to install a separate app called Facebook Messenger.
Even though the built-in Facebook integration with Windows Phone is already brilliant, you can still choose to install the Facebook app from the marketplace.
