What is a UDiD?
Every iPhone, iPod, iPad & ATV has a 40 character long Unique Identifier (UDiD) made up of numbers and letters that are specific to that one device. For example: db72cb76a00cb81675f19907d4ac2b298628d83c
Why do you need UDiD Registration?
Beta versions of iOS will only activate if the device running it has its UDiD registered on a Registered Developers Account. Therefore if you want to try the cool new features of iOS 8 you need to Register your UDiD. After Registration of your UDiD is done you can install iOS 8.
