I had updated a PSP a long time ago to 3.11 and it had caused the WiFi to stop working. It'd give me an error anytime I tried to use it or Ad Hoc. Well I call SONY and tell them this. The bitch asks "Did you put CFW on it?"...."Erm...No? I don't even know what that is." *cough* "Well, wee can't be held responsible for bad updates, you'll have to purchase a new system or send in your current on...".
