I'm having some problems with backing up to iCloud from my iPad. When I first installed iOS5 today and setup iCloud, I used my iTunes account sign in. It synced with iCloud and performed a backup properly.
Unfortunately I then realised that I should be using my old MobileMe account, which I successfully copied across to iCloud and setup on my iPhone. I went in and deleted my iTunes account details from the iCloud settings, and entered in the new account details. This seemed to verify correctly, and I am able to view contacts, calendars etc. stored on iCloud and save documents to iCloud from goodreader.
However when I try to switch on iCloud backup, it displays the error message 'There was a problem enabling iCloud backup'. I have tried multiple times over a number of hours, and on several different wireless networks to no avail.
Does anyone have any ideas where I might be going wrong?
