Yes, you have to be unrooted. And, if you are running the "unofficial" Gingerbread on your phone...the one that many folks flashed (update.zip) back in June, you're going to have to sbf back to Froyo 2.26 before this OTA update will download and install. My understanding from Moto is that this update will only download and install if your phone is running Froyo 2.26 with all updates, last one was 3.8.7, installed.Do I have to unroot first??
