My mother has a 3GS. She keeps getting a message that says she cannot connect to iTunes. She is putting in the correct PW. She tried calling Apple, but they wanted to charge her for a phone call. She tried emailing them, but the response she got did not help her situation and the rep said it was outside of her area of expertise and that was all the help she gave. Any ideas why she keeps getting this message and how to get rid of it so she can connect?
