Registering a UDID for Ad Hoc Distribution
For Ad Hoc signing you need to make sure to pre-register all the devices that you want to run the app on with your unique device identifier (UDID).
If you have a small group of test devices, signing your apps with an Ad Hoc certificate is the most practical way to distribute your app. For Ad Hoc signing you need to make sure to pre-register all the devices that you want to run the app on with your unique device identifier (UDID).
