The best information available will come from Sony in the newest posts to related link
The PlayStation 3 network will work by the end of May, 2011.
You can sign up to the PlayStation Network by going into "PlayStation Network" on the XMB, then click 'Sign Up to PlayStation Network'. Or you can follow this link to sign up on your computer, then transferring your account to your PlayStation 3 console. http://www.us.playstation.com/PSN/SignUp
You have to be 18
First you need a wireless internet connection before you can connect the PS3 to wireless internet. You can not connect the PlayStation without already having internet service. If you have wireless internet service then you go to the PlayStation 3 settings to network connections. If you do not have a wireless internet, but have internet service you purchase a wireless Router and install it first before going to the PS3 setting for network connection. You can also connect a wired system running an ethernet cable from your router to the back of the PS3 and then going to the setting for network connection.
There is no set date. The devastation that the hackers caused could take up to a year to fix, although there is a possibility that Sony may abandon PlayStation altogether.
