Although the signing window for tvOS 10.1 closed yesterday along with that of iOS 10.2, those who are still on the penultimate firmware for the Apple TV 4 may also be receiving some jailbreak love in the near future. A tweet from software development consultant Jonathan Levin confirms that one of the exploits used in the yalu102 jailbreak for iOS 10.0-10.2 can be run on tvOS 10.1, and that as a result, development of a jailbreak is under way.
