I currently have 2.71 on my psp and want to upgrade, so what is the next downlaod I can get? what will happen if I just download 3.72 to my psp? Will it crash or mess up my psp or do I need to download each upgrade before that? I am haveing problems with my memory cards I have a 1 and 4GB memory card for it. And when I put it into sleep mode sometimes the memory card will mess up and say that there is no memory but when I take out the memory card and put it back in it works fine. What is it doing that for?
