I have a gmail email address that I have been using for years to purchase from iTunes. I am planning on using that to set up with iCloud. Now from what I understand, it's going to force me to create a me.com address when I do that. Now would this new me.com address be somehow associated with the gmail Apple ID? And if so, can it be disassociated with my gmail Apple ID at some point in the future and changed to a different me.com address? And is the newly created me.com address an Apple ID itself as well?
