Another method of 1-tap rooting your Motorola Droid has just come out of the shadows!
Universal Androot works a lot like EasyRoot does, but costs infinitely less. Although EasyRoot was removed from the Android market, Unstable Apps introduced a method of using keys to charge for their application.
In search of new methods to root the Motorola Droid, I stumbled across Universal Androot. I tested it on my Droid running Froyo and I can confirm that it can root a stock v2.2 FRG01B Droid.
You can download Universal Androot at Android Super User, and follow the (extremely simple) instructions provided on that page.
As mentioned on that page, if you try Universal Androot with another device please leave a comment about whether it did or did not work.
