I just heard a rumor from a friend that if you update the firmware on one of the backwards compatible fat PS3s, that it will no longer be backwards compatible? This friend is worried as he does not have internet access (shocking!) at his place and has never updated (except for any updates that may be included on game discs?). We're getting together later this month for a LAN party and we mentioned he might need to update in order for things to work right (not sure if that's true either). I have a slim, so I really don't know about this particular feature. I'm searching the net as well, but figured I'd see if any of the subject matter experts here have any opinions on this topic. Thanks in advance for the help!
