How recent are the unhackable PSP mobos?
I've heard talk of an updated motherboard in later PSP slims that is pandora proof. I was thinking of getting a PSP for Christmas and getting CFW on it for homebrew but I'm not sure how big a risk getting a slim is. I've found a good deal for a used slim with a 4GB memory stick and case for £90 and it seems like a good deal but I'd rather not get stuck with a PSP I can't get CFW on to.
Basically my question is: about how big a risk is it getting a used slim?
