An interesting new update from Bing (Microsoft) that uses Facebook APIs to pull in your friend’s information from Facebook.The app enables users to see all of your Facebook friends right in Bing Maps and you can view profile pictures, status updates and write on someone’s wall all from within the application. To get started with the app :

• Start the application, log in via Facebook Connect
• Select “Allow” to allow Bing Maps to connect to your profile (to get your friend list)
• Once logged in, any of your friends who have listed a “Current City” in their profile will have their profile picture pinned to the map.
• More details on the Bing Blog
