A: Microsoft released several applications for the iPad in December 2011, and one of them is an Xbox Live application.
This app, once installed, requires you to enter your Live ID (which is linked to your gamer tag), then gives you information and access to your profile, games played, and messages, and lets you modify your avatar and configure beacons.
The application uses the new Metro style which was just rolled out to the XBox 360 (see the screen shot below).
There is also a Halo Waypoint application for the iPad for tracking your Halo career (see screen shot below) which also looks great!
