I have a 2.2 iPod Touch that I upgraded to 3.0 using iTunes. I jailbroke it yesterday, and all was good. It was running fine, and I restarted it. It showed the apple logo for a bit, then it just went to a black lighted screen. It stayed on the black lighted screen for a minute or so, then restarted. This time when it restarted, it either went to the apple logo, or the apple logo with a little spinning circle. I assume the only way to fix this is to restore, which I'm okay with. However, I wanna know how to keep this from happening. Is it just a random occurrence or did something trigger it?
