Jailbreaking your ps3 is an easy task if you have firmware 3.56 or below. You know that 3.60 and 3.62 firmwares made by sony are tough to jailbreak. But i am sure that someone out there has dualbooted CFW and jailbroken OFW. They are not releasing it because of the recent fight with geohot made them to think twice about releasing.
NOTE : If u have 3.56 version then downgrade it to 3.55 and then follow the steps below :
