Sony have disabled the 'Other OS' option on PlayStation 3 to stop users exploiting the option to hack the console. So, no more Linux on the PS3? not according to George Hotz who wrote on his blog..."A note to people interested in the exploit and retaining OtherOS support, DO NOT UPDATE. When 3.21 comes out, I will look into a safe way of updating to retain OtherOS support, perhaps something like Hellcat’s Recovery Flasher. I never intended to touch CFW, but if that’s how you want to play…”
“And this is about more than this feature right now. It’s about whether these companies have the right to take away advertised features from a product you purchased. Imagine if an exploit were found in Safari on the iPhone, but instead of fixing it, Apple decides to pull web browsing altogether. Legally, they may be within their right to do so, but we have to show them it’s the wrong move for the future of the product and the company.”
Sony say that security concerns prompted them to remove the 'Other OS' option.
