I had used unrevoked3 (NOT unrevoked 3.21) back when I had the Stock 2.1 running on my evo. I recently flashed a stock rooted Froyo ROM, which I've been running for the last few days. If I understand my research correctly, I don't have NAND unlocked because unrevoked3 was not a "full root". What is the easiest way to get the full root now? Can I run unrevoked forever and/or unrevoked3.21 over my current setup? Or would I have to unroot by running a stock RUU, accept the OTA to get back to stock 2.2, and then run unrevoked 3.21?
