Well, we announced that the release of the Xbox Companion application on Windows Phone would take place December 6, you probably also noticed it never showed up on the marketplace. Well, now, the application is finally available, one day later. We can only assume (as not much reason was given for the delay with the application) that the Xbox 360 update problems also somehow affected the Xbox Companion application. Technical problems with the big Fall Xbox 360 update almost delayed the release an entire 24 hours, but late last night the update started populating for Xbox 360 users.
Go get your hands on the Xbox Companion application now and enjoy the magical control your Windows Phone gives you over your Xbox 360 now!
