Facebook for iPhone, iPod touch, and iPad has been updated to version 5.5. New features include an improved button design, intended to make commenting, liking, and sharing easier on News Feed posts, and the inclusion of free VoIP calls for users in the U.S. and Canada, something previously introduced in the separate Facebook Messenger app.
VoIP requires Wi-Fi or cellular data. And, of course, reports of bugginess are already coming in... If you've tried out the latest Facebook update, let me know how it's working for you. If you haven't tried Facebook for iPhone, iPod touch, or iPad yet, grab it from the App Store via the link below.
