The courts have just issued a temporary restraining order against George Hotz (Geohot). Sony filed this lawsuit because they were unhappy that Geohot had released the Playstation 3 decryption keys so other people could play unsigned games on it.
From the lawsuit, Geohot is prohibited from:
“offering to the public, creating, posting online, marketing, advertising, promoting, installing, distributing, providing, or otherwise trafficking” in any software or methods for circumventing the PS3′s protection methods. No longer can he “provide links from any website to any other website” relating to such matters, or publish any information obtained by hacking the PS3. And more to the point, he can no longer “engage in acts of circumvention of TPMS in the PS3 System to access, obtain, remove, or traffic in copyrighted works.”
Pretty much he cant talk or think about the PS3 for some time.
