I need help with my ps3. I just bought a used one from a friend, and I can't wrap my head around whether it's jailbroken or not. Please help me. I found a file named "Dishonored (Game Installation)", but I can't open it or anything. It's around 4 gigs. There are a lot more games like Dishonored on the drive, but none say (Game Installation). I'd really appreciate some help and to give me some insight whether it's jailbroken or not.
