I NEED HELP WITH COORDINATING MY APPLE ID TO MY ICLOUD ID
I got a new iPhone5, and somehow the iCloud user name was set to an old email account of mine which is different from my current Apple ID. ICloud keeps asking me to sign in but I do not know the password. I have tried to reset the password with the old email address but the reset site does not know the user name that I am putting in. I am in a catch 22. When I go to iCloud in settings it is all grayed out and the iCloud drive show it is upgrading but it never completes the upgrade. I have called apple support but to no avail; I have gone to the Apple store and they say I need to contact apple support, Apple Care. I have the latest ios. Any ideas on how to resolve this?
iPhone 5, iOS 9.2.1, 16gb
