As you already know, Apple released last night the iPhone 5 and made us aware that iOS 6 will be available to the public on September 19th. However, if you have a developer account, iOS6 GM (the final version of the OS) can be downloaded and installed right away.
Here’s how to do it:
- Google for iOS 6 GM (you’ll easily find the version for your iDevice) and download it.
- Back up your iDevice with iTunes.
- Launch iTunes (make sure it’s the latest version), click on your device then on the page that has just shown up, hold SHIFT on your keyboard if you’re on a PC or the option key on OSX and click on Check For Updates button, then point to the place where you have your iOS 6GM file and let it do it’s routine.
- If necessary, restore your device from backup and sync with iTunes.
- Enjoy iOS 6.
