https://www.theverge.com/2017/9/12/16277804/apple-ios-11-iphone-ipad-download-how-to >Apple just rolled out the golden master build of iOS 11 to developers and public beta testers today ahead of its official launch on September 19th. This version of iOS 11 should be very close to finished with most of the bugs ironed out, but there’s still a chance you’ll need to download an update on release day. This is the same software build that leaked over the weekend when, so the story goes, an Apple employee emailed public download URLs to 9to5Mac and MacRumors, resulting in numerous eleventh-hour leaks about the company’s announcements for today. They all proved accurate. >But that’s the past, and what you care about is getting iOS 11 on your iPhone or iPad right now. If you don’t feel like waiting until next week, you can install iOS 11 today just by signing up for the public beta program at Apple’s website. Once that’s done, you just open the beta website with Safari on your iPhone or iPad and follow the directions. You’ll download a profile to your iOS device, restart it, and then head to the update menu. Make sure to back up your device before starting the upgrade. Apple spells out how to do that here.
