The iOS release says that as a product in development moves even faster to launch, it has been assigned with a proper codename. Just not only an identifier like “3,1” but also assigned a codename such as N94 (iPhone 4S) or K48 (original iPad). The next-generation Apple TV moved to that step. Thanks to today’s beta release of iOS 5.1, we have codename in our hands for this new Apple TV(3,1).
