Sorry to tell you but the new ps3 "super" slim 500gb is not hackable as of right now. the best bet is to get a used one at a pawn shop.
the only ones that are hackable are ALL the Phat ps3's and some slims.
they must be able to downgrade to 3.55 or lower. to find out if you have a hackable ps3 on you. you can use this file here: [Register or Login to view links] to see if it can be downgraded to 3.55 or lower. when you do get a ps3 with 3.55 or 3.41 firmware on it. its really easy to hack
