Changing iCloud to match new Apple ID?
My apple ID is a very old email address that I no longer use. When I got my new iphone, and ios 5, i put my iCloud account as my apple ID account. Now, however, I would like to change my Apple ID account to a different email address and then use that new email address (my old mobile me address) as the email address associated with iCloud? I have seen things online that you just delete your iCloud account and start all over. That scares me to death, because all of my contacts and calendar and reminders and synced with my iCould, and i really do not want to loose those. So how can I change my Apple ID account email address and then change the iCloud to match that. Bear in mind, however, that the email address I would be changing those to would be a mobile me email address, that is already in existence (which I have heard can cause problems)? All of this, without loosing all of my contacts and such?
iPhone 4S, iOS 5.1, iCloud
