Like Apple's mobile devices, it is possible to jailbreak the latest Apple TV (version 2 black, € 119). This manipulation is permitted through the firmware of this unit, similar to that of iOS. Unlike the first generation that was close to OS X then "hack" and not "jailbreak". The purpose of jailbreaking is to fully exploit the impressive capabilities of the device with software a bit more practical than those offered as standard by Apple.
To jailbreak your Apple TV there is no need for technical prerequisites. However you must obtain a micro USB cable that is not provided by Apple.
