cannot change apple id to my @icloud.com address
hi there,
i am using an old gmail-address as login for apple id and for all icloud-services. I want to change it. I have a @icloud.com mailaddress which I would like to use for my apple id and as a login for all icloud services. But I cannot change it at the apple id page. Apple doesn't seem to accept icloud addresses. But this would be strange. Anyone who can assist me here? thank you very much, Danny
