I have it with latest firmware 4.3.1 has been jailbroken sine day 4.3.1 was released. Today I hooked it up to the computer, adn it wouldn't show up in itunes. Figured it was just a need to reboot glitch, so hooked it to my laptop that i just turned on, still nothing. Plug it into the wall charger, and it doesn't act like i'm hooking a dock cable up to it. I have tried two different cables, and verified both of them are good by hooking them to my ipod. Anyone else ever had this problem?
