I want to have a clean install of the OS when iOS 9 comes however I don't want to lose my notes, or any of my saved data within the apps I use. Is there a way to clean install and just restore data/settings for particular apps? I want all the iOS parts to be fresh (accept I don't want to lose my texts or notes) and I only want to restore saved data from some apps and games. Is this possible or is a restore all or nothing?
