what u guys dont get it's that its woth upgrading if u have 2.1,2.5,2.6 simply because u will be screwed when u want to buy a new game because u will need to update! i see all these people saying your an asshole if u update...but i think ur an asshole if u will rather sit on your ass and wait for a dowgrader or an expliot with full kernal instead of enjoying what the psp is really about playing good quality games peace
