It wasn’t just you that couldn’t connect to PSN, Kevin. I guess there was a serious error with the date/time system on the older “fat” PS3s that was screwing them when you tried to connect to PSN. Seems all is magically fixed now though.
Sony says that there’s a bug in “the clock functionality incorporated in the system”. What that means is that affected systems are resetting their internal clocks to 12/31/99, and this is causing a whole mess of problems including the inability to log into the PlayStation Network, start games and play certain video rentals. In addition, Trophy data for the games you’re trying and failing to play turns into “corrupt data”.
