Best Answer
Your UDID can be used to uniquely identify your iOS device. The UDID is often used to associate actions with a specific known user. Using your UDID, developers' may be able to associate your actions and use of their app back to you.
Apple associate private information with your UDID. You are required to trust that Apple keeps this information private. Hopefully Apple will not sell this information or have it leaked through a security breach. While not highly valuable, if you have privacy concerns consider avoiding participating in beta apps programs.
