iPod touch 5th gen won't sign into any Apple ID
My IPod touch, 5th generation, has never had a problem before and all of a sudden, it won't let me sign into any Apple ID. I've tried signing in with my mum's and my own, but nothing is working. It doesn't say 'wrong password' it just stops trying to log in. Any suggestions would be greatly appreciated. Thank you.
Oh, by the way, I've turned it on and off completely a few times.
