If you’ve jailbroken your PS3 then you probably shouldn’t go online until you reverse the jailbreak. Sony has started banning users who use jailbroken PS3 consoles online! The ban is permanent and worldwide.
you cannot use the PlayStation Network with this account (8002a227).
In the old days it was only Microsoft who were banning their users en-masse but now Sony have to do it as well. I wonder if Nintendo will ever do the same thing?
