I gave my iPad 3 to my sister and she cannot set up her email from gmail I am trying to help her virtually but I do not remember where in settings to set up the email. I am not sure that it was not set up when I gave it to her but maybe now it has something to do with iCloud? I do not remember setting up iCloud when I gave it to her because she was not interested in using iCloud at that time.
