my ipod 4th gen wont let me sign into imessage or facetime.
So while I was texting on imessage, my ipod suddenly signed out of imessage and so I had to re sign in under settings, messages. I entered my apple id and password and then checked off the correct email I had been using. It said it was verifying it but sent me back to the sign in page under settings, messages. I have an ipod 4th gen working with ios 6.1.6 please help.
