I have a new Iphone 5s but can't download my latest Icloud backup as it was made on IOS83
I have a new Iphone 5s but can't download my latest Icloud backup as it was made on IOS83 and the Iphone only has IOS8. I tried to download IOS83 on it but it won't do it as the phone isn't set up yet. What do I do?
