I was just messing around with it, testing out using normal firefox (POPUP blocking is a GODSEND with such little screen real estate). I posted on a forum, and the screen went all grey on my psp, but it still responded for a few seconds before the buttons stopped working. So I turned it off and popped out the memory stick and the thing was hot (not burning hot, but definitely hotter then usual). My PSP was also quite warm. Is this normal for using the Wifi (I just got a router) or could this be a bug?
