FireCore, the guys behind the Seas0nPass jailbreak tool have pushed out an update that provides a tethered jailbreak on the latest iOS 5.0 (iOS 5.1 - 9B179b) firmware. The update to the popular jailbreak tool currently only supports the second-generation Apple TV unit and therefore will not provide any jailbreak on the 1080p capable third-gen Apple TV. The tethered nature of this jailbreak obviously means that every time the unit needs to be rebooted, it will have to be connected to your PC or Mac to be put into a jailbroken state.
