My iPod touch 4th gen is stuck on the Apple logo screen, and every 10 minutes or so it will switch to a white screen with a shadow at the very top, then it will reboot to the same apple logo. I've tried holding down sleep and home at the same time for a while, but it just reboots to the same apple logo. I'm confused, plz help.
EDIT: OK, I held down the home and sleep for a little while longer, and it moved to the screen with the usb cable pointing to an iTunes logo. Does this mean I have to wipe everything on it?
