If you can't get enough of Xbox Live and cry every time you have to leave the house, then you are in luck! A new App has been made available for the iPhone which allows you to manage your Xbox Live profile on the go, granting you the sacred power to accept friend requests, see who's online and send messages.
360 Live is currently priced at $1.99, but Microsoft once declared that any App that takes advantage of Xbox Live should be free, so that price tag could disappear. It's recommended you wait and see if you can get this for free before spending that massive amount of money.
I can't personally imagine ever needing that much access to Xbox Live, but this is still a useful little application for those who are completely obsessed.
