So I have a question about making my transition from 6 to 6S. My current 6 is on iOS 9.1, but the 6S is coming with iOS 9.0. Can I downgrade to 9 without losing anything? I have a back up on iOS 9 but it's a little old and I don't want to use that one. I didn't even consider this situation. Does anyone know how quick the new devices get betas (aka so I can get the 6S to have 9.1 so I don't have to lose anything.) Any help would be greatly appreciated!!
