Facebook Messenger for Android & iPhone is a Game Changer Phone Companies Will Hate

Facebook Messenger from Facebook expands on the messaging features in the Facebook apps for Android and iPhone. It would make more sense to have a single Facebook app instead of two. But, that aside, Facebook Messenger is a game changer that the phone companies are going to hate. It lets you send and receive messages from anyone who is a Facebook friend or in your (Android/iPhone) contacts list.
