Hello! So yesterday I was pulling my iPod (it's the newest one, no idea what generation that is but it's silver) out of my purse and it was tangled in my headphones so as I tried to untangle it I dropped it onto the concrete. It wasn't on at the time so I kept walking, thinking the worst of the damage was a minuscule scratch on the back, but when I turned it on it was just a blank screen. It still lights up and plays music but there's no text or images or anything. Help?
