Facebook for iPhone received an update today that added the features from the standalone Facebook messenger app. If you have a U.S. or Canada based Facebook account you can make free phone calls to your Facebook friends from the message screen. In addition a new button design allows for easier liking, commenting and sharing posts in the news feed.

To make a Facebook call, simply tap on a friends name in the chat menu, tap the information button and another screen will appear allowing you the option to make a call if the other party is available
