Does it make a difference? I created my iCloud account with my old email address.. as was my Apple ID. I've since changed email addresses, and while my Apple ID changed, my iCloud account has stayed as my old email address. The specific setting I'm looking at is under the "Mail, Contacts, Calendars" on my iPhone.. then the iCloud account, then the first thing listed up top is "accounts" it lists my correct apple ID account.. click that and then click 'advanced' and when it lists' the "EMAIL" for my "iCloud account info" it's my old info.. the option to click it is greyed out and I cannot change it. What gives?
