As expected, Microsoft has made its new and improved Xbox Companion app for Windows Phone available to coincide with the latest Xbox dashboard update -- what's not so expected is the iOS app that also rolled out today. Dubbed My Xbox Live, the iOS app (optimized for both iPhone and iPad) is expectedly a bit more limited than its Windows Phone counterpart, but it will let you read and send messages, edit your profile and update your avatar, manage your friend list, and keep an eye on your achievements (and those of your friends). The new Windows Phone app, on the other hand, brings with it a decidedly more integrated experience, including the ability to search for games, music and movies available through Xbox Live, and view second screen information while you're using your console.
