Getting UDID from deactivated device without iTunes or XCode?

Question

I installed iPhone OS 4.0 on my friends iPod Touch 3rd gen and forgot to add the udid to the provisioning portal. The device is locked and I can't seem to find a way to revert it to get the UDID. I don't have XCode here. Using iTunes, how can I revert it?

Answer 1

With the device connected to iTunes, click on its serial number; it should change to the UDID. You can use the Edit > Copy menu item to copy that.

Answer 2

System profiler.... USB.....iPhone.....use the serial number
