Hey, I have an idea and was wondering if anybody has looked into it. Maybe an exploit can be found by looking at the way that backgrounds are changed. I noticed that when you set a custom background in the 2.0+ firmware and remove you mem stick, it stays. So does that mean it is written to the flash in the PSP? If so, maybe you can use that to downgrade or something along the lines of that. I'm a newb at that stuff, so I don't feel bad if I sound stupid, its just an idea.
