Sony Bans Hackers - Hacker Unban Themselves
Found on MegaGames on Sunday, 06 March 2011

A couple of days ago, Sony released its first official statement regarding PlayStation 3 hacking stating that it will ban all hacked consoles from the PlayStation Network and Qriocity service.
A newly released hack claims that it is able to unban banned consoles and ban other consoles even if they are unmodified.
Now all that's left is that a new PSN is launched, without Sony having control over it.
