I was rooted with 2.1 and did OTA update to 2.2. Now I have an unrooted phone with Superuser Permissions apk still stuck on the phone. What I want to get to is a rooted 2.2, but I can't figure out how to do this. I have read some articles saying the RSD lite might help, but I have a mac computer. Any and all help is appreciated. I am a newbie, so I would appreciate specific info. Thanks.
