I just got this second hand ps3 from my friend. It was never jailbroken before. In fact, it was never played for a long time, so I had to reformat it. I reformatted it to OFW 4.83 before I come across this warning not to update it to 4.83 if you want to jailbreak it. Is it too late to jailbreak my ps3? I checked using the minvercheck that mine is 3.50, which is jailbreakable. Please advise.
