Change my "Apple ID and Primary Email Address" to my @me.com address
So I have a gmail email address that I have been using as my Apple ID for quite some time now. When iCloud was launched I added a @me.com address to this account so I could take advantage of the notes syncing feature of iCloud.
I now want to start using my @me.com email address as my only email address and shut down the gmail account completely. Only problem is when I go to appleid.apple.com and try and change my "Apple ID and Primary Email Address" to be the @me one it tells me "You cannot create an Apple ID using a MobileMe account. If this is your email address, it is also your Apple ID".
All I want to do is remove the gmail address off the account and continue using the @me iCloud email that is attached to the account anyway. Why is this proving to be so hard?
