I just bought a psp...its version 3.11...i realize there is no downgrader on it yet...but i just have a couple of questions: 1) After you downgrade to version 1.5, can you just download any random games off the net (actual sony games) and play them? Or is there other things i need to do (other programs etc) before i can play them 2)Can you install programs of choice onto it? (AOL Messenger, MSN messenger etc) or can i transfer movies to my memory stick and watch them? 3)Would you recommend i get a psp modchip? What does a modchip do? 4)What all can i do with a psp? like after all the mods and everything, what is the Sony PSP capable of?
