I want to buy a PSP to put cfw on. Now, i don't know much about the requirements of the motherboard and the like, all i know is that i need one with fw < 5.03 i think. I'm not gonna go for a PSP 3000, as i want a PSP that is fully hackable. So i'm wondering which model to go for.. I would prefer getting a 2000, but i wouldnt mind getting a 1000 to be 100% certain that ill be able to put cfw on. I can't buy off the net, so that pretty much leaves EB Games to buy a preowned one.. I heard about some US PSP 2000's being hackable by looking at the serial number, but im in Australia and am also wondering if any tricks like that work with the PSP here.. I don't want to end up with a PSP that is non-hackable, and want to be pretty much certain that i will be able to put cfw on it. Could you guys give me a hand?
