iOS

I have a 16GB iPhone 6 in the Public Beta program with iOS 9 Public Beta 3 installed, and I haven't received the iOS 9 OTA update yet. My phone is trying to download iOS 9.1 Public Beta 1, and I was wondering if I need to stop downloading that first before I can receive the iOS 9 OTA update. Is there even a way to stop the download of an iOS mid-download?
