How to Find the UDID (Unique Device Identifier) for an iOS Device

You can only install programs that have been approved by Apple on your iOS device (all applications in the App Store have been approved by Apple.) So in the case of beta testing, we need to register any beta customers' UDID with apple. This is Apple's way of approving the beta application for installation.


Email Using a Free App

If you search the App Store you will find out there are plenty of applications to help you find your UDID such as UDID Tool. After you have installed the application to your device, simply email the UDID to yourself or your developer.
