I thought I saw somewhere on here that some people had success in doing the following setup: 1. Cancel MobileMe 2. Use a non-MobileMe email address (e.g. @gmail.com) for their primary iCloud setup. 3. For iCloud Mail and Notes, they were able to use their cancelled MobileMe ID when asked to create a new @me.com address. In other words, their cancelled MobileMe ID was totally deleted and thrown back into the "available to use as a new ID" pile. I cancelled MobileMe 3 days ago, and it still says my ID is still taken with the message: "Email Taken: This email address is already taken. Try picking a new one". I was sure I saw messages in a thread on here saying that some were successful in using their old MobileMe ID as if it were new.
