heh, I'm doing the same thing. recovery is easy to revert on these guys. hopefully you have a backup. if not, i'm sure there's a copy somewhere on here.
as for unrooting, what method did you do? if you exploited the fact that the stock rom already has su, you should be able to just factory reset and call it a day. if you used gingerbreak youd need to run it again to unroot.
problem for me is i never bothered making a backup since i never did anything to really warrant it. but now my touch screen is bunk. plus, the microusb port doesn't work. oh well. i'm sure it won't be a big deal
