So, my iPad 3 is acting up. First off, I just freshly restored it, signed into iCloud, and tried to restore from a back up. That failed because it said "Unable to restore backup". So I did just lose everything in those backups including some semi-important messages. But anyway. I set it up as a new iPad, logged into iCloud and all that good stuff, but when I went to settings, and iCloud, in the storage and backup section it's turned off and every time i switch it on it pops up a black diolauge that says "turning on iCloud Backup" and then quits the settings app. I've restored and reset this thing like 3 times already! Any help?
