Facebook today updated its main iOS app, adding free VoIP calling in the United States and Canada. Facebook previously beta tested the feature in its Messenger iOS app, which received an update to allow voice calling in January. As in the Messenger app, voice calling within Facebook for iOS can be accessed by tapping on a friend’s name in the chat menu and then tapping on the info button, which reveals the option to make a free call. Both parties must install the newest version of Facebook to activate the feature. Facebook’s latest update also adds newly redesigned Like, Share, and Comment buttons.
