I have an incredible myself and can't wait for this method to be official. but i've come across a different project. my buddy saw my customized incredible and wants me to root his EVO. he wants it more for the wifi tethering. but he currently uppdated to 2.2. i know there are several methods to root after the 2.2 update but my question is: how do we remove root just in case he needs to take the phone to sprint for service? thats the only reason thats holding me back from rooting his phone. i want to be able to have everything lined up for him in case a situation comes up and needs to return the phone. if there is a root and unroot process for 2.2 then i wouldn't mind testing. any input is greatly appreciated.
