Depending on how much money you have man, I say just wait for the PS4. Its coming out in 2 months and im sorry but, the PS3s time closing pretty soon imo. With the PS4 right around the corner, its done. Sony will still support the PS3 and all but I think its WAYYY to late to buy a jailbroken PS3 or a modded/custom controller.
not everyone want to buy a $400 buggy ass system that will suck for the first couple of months and that you can't hack on.
I am waiting on the bugs to be fixed, the price to drop, more games to come out, and for jailbreaking code to come out.
