What is UDID?
Every iPhone or iPod Touch contains a Unique Device Identifier (UDID), which is a sequence of 40 letters and numbers that are specific to that device. This is like a vehicle’s VIN number but much harder to guess. Here is an example: 2b6f0cc904d137be2e1730235f5664094b831186.

What can you do with a UDID?
The only way an iPhone can install programs is if Apple approves them. Applications in the App Store have been approved by Apple for general distribution, but beta/demo customers who wish to try the app before it is in the store need to register the UDID. This will allow the user to be approved for use of the application and embed a provision kit onto the phone. This kit will then grant permission so the application works on the device.

How do I get my UDID?
You can copy your UDID from iTunes. Here are the steps to getting your UDID.
