I want to change my Apple ID to my @iCloud.com address because the eMail address I originally used for the Apple ID doesn't work anymore. I now use an @iCloud.com address as my primary eMail address. But when I tried to change my Apple ID to that eMail address I got an error message that said I can't use an iCloud address for my Apple ID. But Apple Care said I could do that, but I haven't found out how yet. Does anyone know how I can use my @iCloud.com address for my Apple ID? Thanks.
