My old, original Apple ID is a @gmail.com address. I realize I can sign in with my iCloud email address or any of its aliases, as all @iCloud.com addresses are Apple IDs already, per Apple. What I'm trying to do is remove any trace of anything @gmail.com as regards Apple IDs, and I can't seem to find a way to do it. I am unable to change my Apple ID to my @iCloud.com address, as you cannot make an Apple ID an @iCloud address -- yet they already are Apple IDs? Anyone have any suggestions/advice? Much appreciated.
