This is a complete mess! Last Tuesday when I updated to the GM 5.0 I proceeded to set up my iCloud account with my Apple I.D and it set up without issue. The problem was I could not back up to the cloud no matter what I did. I figured the service just wasn't full launched yet, right? WRONG! Now I can't even slide the 'iCloud Backup' to the ON position. It proceeds to tell me the 'iCloud backup failed' over and over. Please help!
