We all know that PSP 1000 models are fully hackeable, while 3000 models arent. My question is about the unhacked models. Why arent some 2000 and higher models moddable? Because its already proven impossible, or is it because no one knows how to do it yet? Im asking this because I remember the PS3 wasnt hacked for a while now, but no one said why. I thought that it was because no one bothered on that, but later someone did. Opinions?
