In order for Netflix to work, normally you would need to be logged into the Playstation Network (PSN). However, PSN has been down since April 20, 2011 due to hacking and those with a Netflix subscription haven’t been able to make use of it. Well it turns out there’s a very easy workaround that may work depending on what version you have on your PS3.
You just need to open up Netflix, try logging in 3 times. It will fail the first two times but the 3rd time will simply log you in anyway as if it worked.
If it doesn’t work, I’m sorry, there’s several different versions around and it doesn’t work with all of them.
FYI: I have version 2.02. To check which version you have, before you launch Netflix on the Playstation, press the triangle, go to Information, and you’ll see the version. Let me know which version you have if it does or doesn’t work!
