I don't know though. From what is being said over at DroidMod the one that they have (when they get it working right) should work on 2.2. Who knows though. I think RSD Lite is easy enough and I have just now gotten to the point where I have had to use some. Biggest thing is finding the right sbf to use. Which reminds me, wouldn't be cool if there was a stickied post somewhere that had a list of different SBF files. Like a "Need to return to Verizon so I need to ditch root" sbf and a "Holy crap my phone is stuck at the Red Eye and I have no Nandroid" sbf....just a thought.
