Strange error message "This email address is not available. Choose a different address.".
When I log into my apple ID, I received a screen prompted me to verify my email address. After I entered the verification code received from my email address, and it showed a message "This email address is not available. Choose a different address.". I am not able to log in to my Apple account. I don't understand what happened to Apple, it has simply no logic -- I have my valid email address and received verification code, why it still sell me that email address is not available....Please help me... It has been so difficult to dealing with Apple.
