<p>can anyone tell me the structure of UDID of a iphone . I want to use the UDID to identify each user saperately in my app. The UDID seems to be a 40 digit string . In my app i dont want to use such a big ID. Can any one tell me the structure of the UDID so that i can cut short and make out a small unique string from UDID....</p>
