I upgraded to the 3.0 firmware a few days and when I jailbreak it, it works fine for a while. But when I try to reboot my iPod when I install something like 5 Icon Dock my iPod doesn't turn back on. All it does is show the Apple logo and then the little progress circle. Later the progress circle freezes and then the iPod just shuts off and turns on again and it does that over and over and over till I put it into DFU mode.
