I've been jailbroken on my 3G on 3.1.2, but I'd like to do a clean install, since I downloaded lots of junk, which I later deleted. I basically want to start totally clean and redo everything, since I know exactly what I need now. BTW, I have Categories. I also have aptbackup, pkgbackup, and springback, so this would be a good test for how well these work. So, what is the best way to do a clean install and start from scratch. I was just going to redo the iClarified tutorial: http://www.iclarified.com/entry/index.php?enid=7429 and do Step 2, even though I don't have to. Any thoughts?
