PSN has finally returned online in North America and will soon be online everywhere else in the world.
It will slowly gain back all it's functions by the end of May, 2011. As most of you already know, PSN was attacked by a group of hackers called the Anonymous.
PSN should now be safer and harder to hack.
Also, every PSN account has to change their password, but that can only be done from the PS3 that the account was registered on. Though password change can also be done through e-mail validation.
