On XDA Developers forums, Shadowmite wrote about their accomplishment:
"Yes, we got two phone's rooted. I will update here if we find a way to make it likely and/or with more details. But suffice to say, at the moment its not very repeatable. We are working on many methods still, but this will be useful in many ways.
The wiki at unrevoked.com mentions that "This hack is for power users only right now, and is not as simple as unrevoked is. We are working on expanding the race window."
Engadget adds however, that "The important thing though, is that it's happened, and we're now probably only a few days removed from a user-friendly patch that lets us truly do whatever we might want with that handsome device. "
