I purchased the 3.0 os for my 2nd Gen non-jailbroken iPod Touch. The update went fine, and after it did everything, I disconnected it as usual. I recently got a game through iTunes so I hooked up my iPod to sync it, and it ran it's usual back-up routine. It reached about 20% and stayed there for almost an hour before I gave up and canceled it. I disconnected, restarted the iPod and my computer and tried again. Now it's hanging at the back-up status with the animated striped bar (before the actual back-up process) and has been for nearly a half hour. Has anybody else experienced this? Did you find a solution?
