Facebook Launches Messenger Mobile App [blog.facebook.com]

So today, we're introducing Messenger, a new mobile app that simplifies how messaging works, and gives you a faster way to message friends and small groups. Messenger is a separate app, so it only takes one click to get to your messages or send a new one. Messages are delivered through notifications and texts, so your friends are more likely to get them right away. You can use Messenger to reach all of your friends -- whether they're on Facebook or in your phone contacts. All you have to do is type the person's name.
