HTC Incredible :: Have Rooted 2.1 Confused As To What Happens When OTA 2.2 Hits

I've rooted my DIncredible, and have S-OFF through unrevoked. I know that when the OTA hits, I will lose root access. But with S-OFF I will be able to re-root.My question is, how would I go about doing that? Is my phone safe to let the update go through? Also, I've read around, but there's no all-inclusive guide that I can see that has how to get root back once I get the OTA 2.2.I'm kind of wary about using a leaked ROM instead, but that might be the easiest way to do this and keep root unless there's a guide out there.
