I just upgraded to iOS 5.0. I am debating on whether or not I should take this opportunity to get a new .me Apple ID and email address from Apple. I understand that each iDevice is eligible for creating ONLY ONE new .me Apple ID and email address. My question is this: If I choose to use an existing Apple ID (including another .me address that I created from a different idevice) when I upgraded this current idevice to iOS 5, do I somewhat forfeit my opportunity (or quota) to create a NEW .me Apple ID later on to use with iCloud? Does Apple automatically associate the first Apple ID sign-in (even if it is an existing Apple ID) to the idevice as the PRIMARY id for that device so that it could not be changed later? My dilemma comes from the fact that all variations of my real name for a .me Apple ID had been taken by someone else, so I need time to think up of another one. Help?
