latest update not only disallows cellular settings to stay set but also disabled the App store. (iPhone 4S) I can't even begin to figure out how to fix this.cannot set "do not disturb" to manual, like it was before the upgrade either.


Try updating to iOS 9.0.2, it's yet more bug fixes.

  • update 9.0.2 came to my phone at 3am last night - it fixed this issue.
