Frequent Questions

Why do I have to register my UDID with Apple?

Apple will only activate iOS 12 beta software if the device’s Unique Device Identifier (UDID) is registered with the Apple Developer Program. Before activating iOS 12, 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 12.

What is a UDID?

Every iPhone, iPad, iPod touch, Apple TV, and Apple Watch 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, open our configuration profile to easily find your devices’s UDID.

How long will registration take?
