Mobile Facebook Messenger Update Adds Emoticons, Shows When Friends Were Last Active

Shortly after Facebook announced an upgrade for Apple iOS devices and said it was working on improving the Android application, the team behind the site's mobile Messenger app released an update that allows users to see when their friends were last active. Facebook is in the process of rolling the update out for Android and Apple users, who can now use emoticons and gain one-tap access to their friends' timelines.
