Why do I have to register my UDID with Apple?
Apple will only activate iOS 17 beta software if the device’s Unique Device Identifier (UDID) is registered with the Apple Developer Program. Before activating iOS 17, Apple verifies that the device is registered. If you have registered your device’s UDID with Apple in advance, you can easily install and activate iOS 17.
What is a UDID?
Every iPhone and iPad has a 24 or 40 character Unique Device Identifier (UDID). Your device’s UDID is not its serial number; the UDID and serial number are very different. If you reading this on iOS, download our configuration profile and then go to Settings Profile Downloaded to find your devices’ UDID.
