How do u delete iCloud account or CHANGE the email address?

Question

Long story short, I ended up having to restore to factory settings my iphone.  I had planned on restoring one of the backups that I had done through iTunes.  (Yes, I now know to backup through iCloud so please do NOT suggest that -.-) but it kept telling me that there was a threat detected in the backup file??? So skipped it. And tried again. Didn't work. Got same msg about the threat. So I ended up healing the threat and then it told me that it couldn't restor the backup because a file was either missing or corrupted. I'm like..***!!! Ughness.
So now I'm trying to set it up so that I can back it up via iCloud so that this stupid issue doens't occur again, but my old @rogers.com email address is the iCloud email addres and I'm trying to change it in the iPhone to my @bell.net email address.  I have changed it in itunes.  It's working there...but my stupid iPhone keeps asking me for the password on the Apple ID that has the @rogers.com email address. THAT IS NOT THE EMAIL ADDRESS THAT IS SET UP IN MY APPLE ID! I have already set up the new one....which is the @bell.net one but for some stupid reason, iCloud keeps wanting the @rogers.com one...and whenever I enter it, it's not correct because that email address has been removed.
Can someone PLEASE help me.
Thanks

You can't actually terminate an iCloud account, though obviously you can simply log out of it on all your devices and then ignore it in future.
I gather that the @icloud.com address is also the actual ID? You can't change that. However if your Apple ID that you use to log into iCloud is a non-Apple email address you can change that - please follow carefully the instructions here:

If it's this non-Apple address which is compromised then changing the ID will solve that. If it's the @icloud.com address which is compromised then you cannot change that though you can add up to three 'email aliases' - these are additional addresses (not accounts) which deliver into the same inbox as the main account. (In fact it's a good idea to give out alias addresses, rather than the main address, because if they attract spam you can easily change them.) (New aliases can only be @icloud.com ones; @me.com addresses cannot now be created.)
You should be aware before you start that once you've created an alias you cannot turn that address into a full iCloud account or move it to another account.
More information on aliases here: http://help.apple.com/icloud/#mm6b1a490a
However if you add an alias the original address will still function, so if you are getting a lot of spam it will still arrive.
You can get a completely new iCloud account simply by creating a new Apple ID at http://appleid.apple.com , for which you will need a new non-Apple address which has never been associated with an Apple ID.
You will need to sign out of the old account on all your devices and sign in with the new ID.
If none of this solves the problem and it is a security issue, go to https://getsupport.apple.com ; click 'See all products and services', then 'More Products and Services, then 'Apple ID', then 'Other Apple ID Topics' then 'Apple ID account Security'.
