The Xbox app for iOS has been updated and has brought some pretty cool changes.
You can now use the app to play movies, start games and launch apps. The iPhone will act as a companion to your xbox and you'll have to run through a setup.
I can see this coming in very handy for those that use the Xbox as a media centre.
The ability to start and stop and select media using the app makes live a lot easier if the Xbox is in a different room.
