The fact confirms earlier speculations that Apple TVs run iOS. iPhone Dev Team members ran it through an in-development iOS 4.1 hacking tool they developed called SHAtter. They quickly extracted the cryptographic key used to lock down the Apple TV firmware, which is the first step in finding a reliable jailbreak.
It's unclear exactly what could be done with a jailbroken Apple TV. Compared with other iDevices, it has a paltry amount of storage space. And, of course, there's still the prospect that Apple will make last-minute changes to Apple TVs that patch the vulnerability SHatter exploits.
