Not aware fully of the situation,
But there is an error for the PS3 FAT (Don't Worry Slim Users )
This information is from a friend that has a PS3 Fat and he did some internet searching.
Heres what he said he found. Doesn't make it fully accurate but could be.
This is all what my friend said he read on the internet. Could or couldn't be accurate."Every FAT PS3 got the 80050F error which has damaged the ability to sign into PSN and games with trophies can't be played because the trophy system has crashed. The date on all PS3 Fats also got set back to 12/31/1999. People are saying it has something to do with the leap year that set the clock back. Since PS3s weren't made in 1999, they don't register with PSN and the trohpies system, causing everything to crash."
