I need to know, also.
I had a .MAC account which became a MobleMe and then I transitioned to iCloud. I just received a new iPhone 4S and, when setting up the iCloud account on the new iPhone I typed the email address incorrectly. How can I delete the new account, which has the correct Apple ID and wrong email address? I have gone to AppleID @Apple.com and verified the correct email address is connected to my Apple ID.At iCloud.com/#mail I went to preferences and can add or delete an alias email address but can not delete the primary. When I try to change the email it says that email is already taken.
