What's a UDID?
Your device (e.g. iPhone) has a unique identifier called a UDID. Your UDID allows us to activate that device so it can run iOS beta software. Nothing malicious can be done by knowing your UDID so it is perfectly safe.
Where's my UDID?
Please note: Using an app to find your UDID will give you an invalid UDID (beginning FFFF). This method was stopped by Apple a few years ago. Please use one of these methods to obtain your UDID.
