So how does the iOS 10 beta work with the current OS's? I use an Apple Watch, and iMac. When my iPhone 6s Plus talks to them or iCloud is it going to freak out? I've made an encrypted backup in iTunes and I don't store anything locally on my iPhone so it doesn't matter if it gets wiped, but could I lose iCloud data for example? Photos, workout app data, email, contacts, calendar?
