ps3 jailbreaking 4.00

im somewhat new to hacking and i need someones help with jailbreaking my ps3. i have 4.00 firm ware. do i need to have a previous firmware? if so is there anyway to get that previous firmware back so i can jailbreak? please help.....thanks in advance.

I don't think there are jailbreak for version 4.00 yet.

probably wont be either.

There is already one..How to Jailbreak PS3 4.00 | How to Jailbreak PS3 4.00

this is all fake ****** bullshit.

I think that one is fake. Anyone to confirm?

I think that so far, There is only ONE way to hack it. You need a mod-chip. If you want to go online, jailbreak an older ps3 (with 4.00) and have another legit ps3 and just convert the hacks into game saves. I think thats what one of my friends did.

Did the 4.0 is the last ubdate that append like 1 week ago maybe a little more ??? cuze if yes I need a jailbreak then

Will you get banned if you hack without a jailbreak ???
