Apple just announced iOS 9, the next iteration of the operating system that drives and powers Apple’s mobile devices, like the iPhone, iPod touch, and iPad at WWDC 2015. Officially, beta versions can only be installed on iOS devices if UDIDs are registered with Apple. To register a UDID, you need to be a developer or have someone with a developer account, and can register your iPhone or iPad’s UDID. As long as you have access to a firmware file, it appears that you can go ahead and install iOS 9 without registering your UDID with Apple. Simply connect your iOS device to iTunes using the supplied USB cable and install away using the ‘Update’ button while holding down the Option key on your Mac, or the SHIFT key if you’re on Windows, next selecting the required iOS 9 firmware file to proceed as you normally would. This is very simple and can be done on any Mac or Windows computer.
