(adsbygoogle = window.adsbygoogle || []).push({}); ok so i havent used my ps3 since september of 2011. i havent took it out the closest yet because i want to hack it and i dont know what filmware its on so i dont want to waste my time. can anyone tell me what was the last filmware released in september???

How lazy? turn it on and look

I'm not quite sure what firmware that would be, but follow this:
Settings > System Settings > System Information

That will get you to your current firmware Good luck in hacking it! Remember not to brick it :p

Do what Chaz said as we would have no clue as to what firmware would be on the console. (Could be any update from when the console launched) It only takes 30 seconds of your time.
