When should I give out my iPhone UDID? A company is developing an application for my company for the iphone wants my UDID. Are there any risks to me as an individual giving this out? Many thanks
You should give out your device ID whenever you want an application that is not in the store (or a version not in the store) to run on your iPhone. The developer needs to add that device ID to a list of devices that can run the test version he builds.
(And it's a distracting process for him, so best answer right away before he gets involved in something else.)
The worst thing that can be said about the device ID is that it absolutely identifies your device. No other iPhone will ever have that device ID.
