Ever since Windows Phone 7 launched with Xbox Live integration, our hopes for an official Xbox Live app for iOS died a miserably lonely death. But it was all in vain, because Microsoft this morning snuck out an official iOS app for Xbox Live users.
It's fairly extensive, offering similar functionality to the WP7 app. You can view the latest videos in the Spotlight section, manage your Avatar in the Social section, including the ability to send messages and add/remove friends, and view your Achievements and Gamerscore in the Games section.
It looks just as slick as the WP7 app, with similar Avatar animations while browsing through the app. It's a nice effort, and well worth the free download.
Now all we need is an Android version...
