Here's a link to a good guide for me, I think?

Nexus One with Froyo Rooted-Easy Step by Step Guide Gadgets | Technology Simplified


1. I already flashed froyo and computer saw device, so do I need SDK and can I copy any files just to SD Card intead of SDK, if I can skip the SDK step. Do I need to rename like to "Update" as we did in the 2.2 upgrade?

2. After Bootloader unlocked can I flash ClockworkMod from Market instead of flashing AMON. Unless Amon is that much better.

3. Then flash the quickrooter per the the listed steps.
