Apple has released the final version of iOS 8, known as the Golden Master (GM) build, to those registered with the iOS Developer program. The final build is 12A365, and is notably unavailable as an OTA download from existing iOS 8 beta releases.
Developers can gain access to and download the appropriate iOS 8 GM IPSW files through the iOS Developer Center. The supported hardware remains the same as the earliest beta builds, including iPhone 4s, iPhone 5, iPhone 5s, iPhone 5c, iPad 2, iPad Air, iPad with Retina display, iPod touch 5th gen, and both iPad Mini models. New iPhone 6 models will ship with iOS 8 preinstalled.
Because of the inability to use Over-The-Air update from an existing beta version, the best thing to do is to install iOS 8 GM fresh, or to update over an existing iOS 7 installation. As most developers know by now, that’s good practice for updating from beta software anyway.
The final release of iOS 8 will be September 17 for the wider public, making now an excellent time to prepare your iPhones and iPads for the iOS 8 update before it becomes available. With that said, technically anyone can install the iOS 8 GM builds as long as they have iTunes 11.4 installed on their Mac, so if you have a friend in the developer program and you’re antsy to get your hands on iOS 8, you could head over to their house and install it – and no, we’re not recommending anyone do that.
