This topic is only for getting the UDID of an iOS device for use in our beta testing teams. The ID obtained by following these instructions CANNOT be used to license a device, it is ONLY USED FOR BETA TESTERS!
Finding your UDID using iTunes
Open iTunes (the Mac or PC app, not iTunes on your iPhone).
Plug in your iPhone, iPod touch or iPad.
Click its name under the devices list.
Ensure you’re on the Summary tab.
Click on the text that says Serial Number. It should change to say Identifier (UDID).
Select Copy from the Edit menu.
Your UDID is now in the clipboard, so you can paste it into an email or message.
