How to find the UDID for an iOS device
You might need the UDID for an iOS device if you need to install software via adhoc distribution. The UDID is a secret number that identifies your hardware. It is used by Apple to authorize an app to be installed on your device without going through the App Store. You probably will not need this info unless an Apple Developer has requested it, so they can authorize your device to work with their software.
