Concerning updating the iTouch 5th gen.

Hi everyone, I finally manaaged to update my iTouch 5th gen. I got stuck at 83%. I tried a couple of times, but had no success. What finally worked was closing the settings out of the app switcher, then completely shutting down the iTouch. I then turned on the iTouch, and when the iTouch was all booted up I went back and tried the update over the air, it worked fine. So just another suggestion for doing the over the air update, if you get stuck turn off the iTouch and reboot it, then try again.
