I signed up for an iCloud account with a different user ID email and before the new IOS 5.1 update. Then, I did the update, and changed my user ID email and purchased some more storage. Now, I cannot download the storage because the user ID is not matching my new ID. When I sign into my iCloud account and try to change it, the user ID email is grayed out. The only thing I can change is the password, which does not help me.
