Do you have some questions? Check out our FAQ and see if it
can't help answer some of your questions. Why do I have to
register my UDID?   How long does it take for my UDID to be
activated?   Do I have to use a Mac operating system?  No, you
can use either Windows or a Mac. Just make sure you download the
latest beta of iTunes. Please note that apps such as InstaSign
do Mac OS, however, this can be installed using a virtual
machine inside of Windows   Each device you use has a unique
UDID. Therefore, you must pay to register each of them. If you
purchase more than 1 activation at a time, you save 10%.    img
