3.56 PS3 update
I know this opic is in the PS3 forum but I think more people would see it here. There has been a security patch for ps3 that disables the GeoHot jailbreak. A.k.a. No more challenge lobbies as far as I know. Before you update... if you are on a custom firmware, RESTORE IT TO THE ORIGINAL FIRMWARE before you update to 3.56. If you try to update with a jailbroken ps3 you will get an error around 9-20% throught the update. It's been updating on my ps3 for about 20 minutes and it's only 63% done. So this must be a big update. Ok well I'm done for now lol. If this helped press thanks
