Some crazy programmers have overclocked the Droid to 1.1GHz, making it faster than the Nexus one. The Droid usually runs at about 600MHz so bumping it up to 1.1 was fairly dangerous. However, with a little tweaking the boys at AllDroid were able to find a stable speed at about 800MHz.
How do you do it? Well, it requires you to root your Droid, a fairly simple process and then upload a new bit of firmware. The full instructions are here.
As someone who has tried to futz with firmware, this second step is pretty rough so get yourself a few bottles of beer before you start.
