What happens if I choose Reset All Settings?
My iPhone is giving this popup that says: "Unable to Purchase: 'The Simpsons Arcade FREE' and 1 other item could not be purchased at this time. Please try again later." frequently when I try to update or install any app. (The app installs fine though.) Apple Care suggested I choose Reset All Settings to get rid of the problem. My question is, what exactly happens? Do settings and preferences in the apps get deleted too, or just system settings?
