So I have decided to stop at the iOS 9 beta and am waiting for the final release to be out next week. However, iOS 9.1 beta has downloaded itself to my phone and I get some message saying it will auto-install next morning between 3 to 4 am. I have no desire to install 9.1 beta. It has been a fun ride, but I am prepared to return to using my iPhone "as is". Is there any way to delete the file from my phone? The (1) badge is also quite irritating. Thanks in advance for your help.
