Getting Your iPhone Device ID (UDID)
What is the UDID?
Each iPhone or iPod Touch use a Unique Device Identifier (UDID), which is a sequence of 40 letters and numbers that are unique to your device. It’s similar to a serial number, except that it’s much harder to guess.
Why do we need the UDID?
Our Early Customer program lets you try out new applications and features before they are available in the iTunes application store. Your iPhone can only install programs that are approved by Apple; for example, applications in the iTunes store have been approved by Apple for general distribution. For our early customers, we make a request for Apple to approve our application especially for your iPhone. We do this by telling Apple your UDID.
How do I get my UDID?
You can copy/paste your UDID from iTunes or email it directly from your device by using a special free application from the iTunes application store.
Emailing your UDID with the free “Ad Hoc Helper” application
