Facebook has updated its Messenger app with the capability to record a voice message for your Facebook friends. Users will now have an additional tool to communicate with your friends in addition to using the standard texts and photo messages.
Facebook will also soon be integrating a VoIP service into the Messenger app. As of this writing, the Facebook Messenger free calling service is in beta testing in Canada only. Facebook has promised to expand the services to the U.S and Europe.
Until then, Facebook Messenger v2.1 is available as a free download in the App Store. Facebook Messenger is compatible with the iPhone and iPod touch.
