Given Sony's track record, the first thing that comes to mind is that it could be possible it's a two step rocket in patching some vulnerability. Just saying, I wouldn't expect them to just idly stand by regarding recent events.
Hi everyone i'm new member here but have been using ps3 jailbreak right from start. FYI: just want to let you guys know that on 4.31 update you cannot use multiman and you dont get the option to play back up games. I installed it on my ps3 and get an error when playing back up games.. As it was said it was just a minor update!! its not a minor update..
