Last week a group of hackers, aiming to restore original functionality (later removed from all consoles, even those already purchased, by Sony software updates), published rootkeys to the system, allowing 'jailbreak'-like exploits. Trying to shut the stable door after the horse has bolted, Sony has turned to the courts to defend the PS3 from 'jailbreak' endeavours, seeking an injunction against the actions of the "fail0verflow" group, which insists it is not planning on engaging in video game piracy, but on unlocking the full potential of the PS3's powerful hardware.
