Everyone is always so concerned about unrooting, removing su, removing busybox, etc., and so-forth. Well, finally an extremely simply solution. Almost too simple. Go to the Market and install SholesMod Updater. Sure it's $5, but it does it all for ya. Just install the app like any other, then open it. Select "Stock 2.0.1 (No root)" and let it do it's thing. TaDa! And no one is the wiser. Hope this puts some minds at ease.
