I have GT5 and my PS3 screaming at me to upgrade so I can play the game. It seems as if the only way to play this game from a JB PS3 is to have an original disc. But that is not possible yet. While the battle is being fought by the hackers, I'm thinking that perhaps I should update to OFW 3.50. But I don't want to risk the ability to JB my PS3.
So I would like to know, has anyone here successfully downgraded from OFW 3.50 and managed to JB their downgraded PS3 without issues?
