Change AppleID to MobileMe and move account

Question

I have an existing Apple ID that gives me access to all my music in iTunes, and I recently qcquired a MobileMe account which now now become my primary (only) personal e-mail account.
Obviously, it would make sense to change my Apple ID to reflect my MobileMe email account. Unfortunately, the system says I can't change my old Apple ID to an existing Apple ID (every MobileMe account generates it's own Apple ID).
So how do I move my account history and iTunes music access over to new MobileMe Apple ID?
PLEASE HELP!!!!

Haha, I had these same issues to when setting up one of my accounts, except it would default to POP instead of IMAP.
To delete your account go to 'Email' -> Preferences & Accounts -> Select Your account under 'Accounts' Scroll all the way down and click 'Remove Account'
Your pre will chug along for a few minutes while it deletes the account.
Once you have an account setup, there is no way to change the server type, you have to delete and then add your account again with new settings.
So, from under emal 'preferences and accounts' click 'add an account'.  Instead of typing in your emal address and password like it asks, go ahead and hit the email menu and select 'manual setup'.  In this screen you can set up the server type, port numbers, encryption etc etc.
Hope this helps.
