Why are you unrooting... From another area on the forum:

You're asking a couple of different questions.

Getting root access on a Droid ("rooting" means something else, ask an Australian), in and of itself, does not void the warranty.

The warranty, in part, reads:

Unauthorized Service or Modification. Defects or damages resulting from service, testing, adjustment, installation, maintenance, alteration, or modification in any way by someone other than Motorola, or its authorized service centers, are excluded from coverage.

Getting root access won't damage anything. If you use root access to overclock, and your Droid fails, it is not covered under warranty (there is a reasonable presumption that if you modify it so it is working beyond specifications, damage is due to that modification).

Your second question, "how could they tell?," is only meaningful to someone looking to be dishonest, and trying to conceal damage which would not be covered by the warranty. Whether or not they can tell, if some modification you do causes your Droid to break, you can't honestly ask for Motorola to fix it.
