Facebook has updated its iPhone app to version 3.4, bringing with it some new features for those who care and giving users the chance to unfriend people on the go if they've fallen out with them.
In what is no doubt likely to start a massive refining of friends, the new iPhone app allows you to ditch those that aren't in your good books at the press of a big shiny red button.
Of course it is not all about showing your unfriendly side. New to the mix are a map view for Places, the ability to check into Events that you’re attending and an improved News Feed inferface. There is also the promise of better notifications within the app.
You can get the update free on the iPhone by heading over to the App store and pressing, you guessed it, update.
