What is My iPad's Unique UDID

A unique device identifier (UDID) is a 40-character string assigned to certain Apple devices including the iPhone, iPad, and iPod Touch. Each UDID character is a numeral or a letter of the alphabet. Using the UDID, Capit Learning can allow certain users to beta test early versions of CAPIT Reading.
