Microsoft just updated its My Xbox LIVE app to include functionality for controlling content on your Xbox from your iPhone (or iPod touch). The app previously let you access Xbox LIVE achievements, connect with friends, and change your 3D avatar, and now it lets iPhone users “connect, control and discover content” from their console through a number of new features. Among them are a remote with “play, pause, fast forward and rewind” and a new Quickplay list of recently viewed Xbox content. The update also brings high-resolution images and improved authentication for iPad, but no support for the new controls.

Earlier this month, Microsoft previewed a new AirPlay-like wireless streaming app called “SmartGlass” that will allow users to share video content from their mobile devices (iOS included) with their Xbox. The previewed app will also include integration with Xbox games, but Microsoft only mentioned Windows 8 support for those features.

A full list of new features in version 1.5 of the My Xbox LIVE app is below:
