its unbelievable, but according to eurasia.nu
wow, is this an Easter-Egg from PS3 system engineer? O_o"Finally Paradox decided to release the PS3 exploit, and guess what, it's really easy to use! All you need is the PS3 controller and a secret button combination during PS3 boot which will disable the disc protection. You can load any backup after this!! To enable the exploit press the following buttons at the same time on the PS3 controller after power on; L1, L2, R1, R2, SELECT, START, TRIANGLE, SQUARE, press and hold while rotating both the analog sticks clockwise slowly then tap X distinctively once. It takes a while to get a hang of it, but it is worth the effort. Please note that some buttons might be hard to reach at the same time so get a friend to help or use your feet to aid."
