So just decided to say eff and went ahead to try to root my phone without unrooting my 2.1 root files and used the 2.2 Droid 2 root guide and surely enough I'm rooted... I think? I could use Root Explorer again but when I went through the App drawer I couldn't find my Superuser app anymore.. odd right? So I'm guessing I don't need it? Or what steps should I take to put the app back?
