Facebook has released a stand-alone messenger app for the iPhone, iPod Touch and iPad. The new Facebook Messenger app is a lot faster to use when messaging friends than the Facebook app. If you enter in a telephone number you can even get mobile notifications so that you don't miss a message. Best of all, the app is free at the AppStore.

Here are some of the top features:
  • Message friends, groups of friends or anyone in your mobile contacts
  • Map your location, find your friends and make plans on the go
  • Get mobile notifications so you never miss a message
  • Include photos so friends can see what you're doing
