Thanks for this. It gives me a little hope I could be fairly well covered here perhaps but I'm a little in the dark about how I am currently backing up as I "think" my iPhone backs up to the cloud? How can I check this and check its made all the backups (before) I upgraded to iOS Beta? So option 1, how do I go about installing the same beta version on it as I was thinking I have to register it under my icloud to get that far don't I? Or does it go through the options and then decide to pull the Beta 18.0 down? Hope that I am asking the right questions?
