Sony made the move on April 1 with the idea that it would make the consoles more secure.
Geohot who is known to the authorities as George Hotz posted a blog stating that he’s planning to figure out a way to update and retain the “Install Other OS” support.
His cunning plan involves a technique similar to Hellcat’s Recovery Flasher.
Geohot, who is better known for his jail breaks of the iPhone, meanwhile is calling on those who want to continue to run Linux on the PS3 to skip the 3.21 update.
He said people paid for Linux on the machine and it was not good that Sony was taking it away.
While Sony claims that unauthorized access via the Other OS window could compromise security on Sony Playstation Network, it has not said how. It has also warned that if users don’t update they can’t sign into the PlayStation Network, use “online features of PS3 games and chat, or play Blu-ray discs or games that require 3.21 or higher.
In addition, those who don’t install update 3.21 will not be able to play copyright-protected videos that are stored on a media server “when DTCP-IP is enabled under Settings,” says Sony.
Some Linux users are actually miffed with Geohot. They think it is his earlier PS3 exploit which is responsible for Sony flicking the switch.
His exploit hacked into the PS3, giving “full memory space access and therefore ring 0 access from OtherOS.”
