Facebook has been working hard on its iOS app, with several updates launching recently. The latest free update hit the App Store on February 22. Most visible are new sharing buttons, which are simpler to use and provide an easier way to like, share and comment.
Free in-app calling is now officially a part of the Facebook app for iOS, making it possible to call your friends in the US and Canada without using voice plan minutes. The feature will of course use up some of your data plan as these calls are placed over the Internet.
