Long story short... I backed up my iPhone 7 yesterday using iOS10, and now looking to restore this backup to an iOS9 iPhone SE setup device. iTunes is not allowing me to do so, without upgrading the iOS9 to the new iOS. Is there anyway around this? I'd like to keep iOS9 as I like the swipe to unlock feature, among a few others. Let me know, if not I guess I will just update the phone to iOS10. Thanks!
