I see all kinds of "unroot" or "factory reset" stuff flying around but nothing specific to me. I rooted in 2.1 and then me being dumb and not knowing enough about this updated to 2.2. The phone still works but I no longer have root (understandable) however I still have the superuser permissions and such on my phone. I would like to reroot but I want to get it to "stock" 2.2 or even 2.1 if I have to before I go that far with it. Please help!
