This is just a warning for anyone and everyone planning on running the upgrade to iOS 8.2 on their Apple devices. I ran it last night and found that it deleted my music, my playlists and my audiobooks.
One of which I hadn't had a chance to backup.
So I spent roughly an hour chatting with the nice guys at Apple who re-set the download on the latest audiobook. This one was a fabulous one and I didn't want to lose it.
Needless to say, I got it back and it has now been backed up - on three different drives.
