So I already had an @gmail.com existing Apple ID and when I signed up for MobileMe apple gave me a new @me.com Apple ID. I made some Apple purchases using this ID but now I will be closing the MM account and I would like to transfer/merge my @me.com account over to my pre-existing @gmail.com account so I can retain my purchases/records. Anybody have to do this before? The process is not immediately obviously... do appreciate any help.
