I am currently running the iOS 9 beta 5 on my 5S. I didn't make a backup before installing the beta, dumb move I know, and I do not have a computer so I don't have iTunes. My question is about the update process. What is the best way to get the newest non-beta version of iOS 9? I am getting update requests on the phone for a newer beta but I am not interested in any more beta versions of software. How do I go about getting the full version and how long do I have before my beta expires? Thank you for the help.
