Good news to gamers and particularly Playstation 3 owners the PSN is finally back online. The main functions like online gameplay, chat functions, Qriocity services and of course Playstation Home are operational. It's a relief for gamers since the Playstation went down on April 20th, almost 4 weeks ago. Playstation Users will have to install the mandatory PSN update 3.61 and change their passwords on the PS3 they originally registered on. For gamers who do not have their original PS3 they can change their passwords through an authenticated email from Sony.
