Read the ENTIRE article before asking any more questions. Hopefully you synched the devices at least onece with iTunes.

If you did not synch with iTunes, try the solution detailed in stevejobsfan's post. That will work assuming you registered your device with Apple. If not, you will most likely never be able to find your serial numbers.
