itwbennett writes "On Friday, George Hotz, best known for cracking Apple's iPhone, said he had managed to hack the PlayStation 3 after five weeks of work with 'very simple hardware cleverly applied, and some not so simple software.' Days later, he has now released the exploit, saying in a blog post that he wanted to see what others could do with it. 'Hopefully, this will ignite the PS3 scene, and you will organize and figure out how to use this to do practical things, like the iPhone when jailbreaks were first released,' he wrote. 'I have a life to get back to and can't keep working on this all day and night.'"

to gain unrestricted access to memory. It seems the trick is to use a pulse to glitch the hypervisor while it's unmapping memory, leaving a favorable page table entry."
