My iPod Touch is frozen after restarting
I restarted my iPod after it was failing to install an app, and it's been frozen on the apple logo for 20 minutes. About 15 minutes in it flashed to almost all white, then went black, then went to the apple logo again. I've tried restarting it, plugging it into iTunes, and charging it. Currently it is plugged into my charger next to me.
Usually, my iPod only takes a minute or two to reboot after restarting. What can I do to stop it being frozen?
iPod touch (4th generation), iOS 6.0.1
