I just rooted my Incredible a couple hours ago. I had never rooted a phone, and was a little worried. However, I found a very thourough and good guide, and all went well. The guide can be located at
Howto: Root the HTC Droid Incredible - Technology - Jonamerica.com
A few things that had me worried. One was the fact that I couldn't figure out how to get out of HBOOT from my device. I still don't know how I did it, but possibly the same way I got in...Hold down Volume - and Power.
The second thing was when I was instructed to go into Device Manager and update Android Drivers, they listed it in the guide as "Android 1.0" under "Other Devices". I'm not sure if it was because I used Windows 7, but there was no "Android 1.0" or "Other Devices". However, there is "Android Phone" in the main menu, so I just used that instead of "Android 1.0". Worked like a charm. Seems obvious, but I get nervous when everything isnt exactly like it is explained lol.
However, everything was pretty straightforward and easy. It is a detailed guide and now I am loving root on my Incredible.
