I realize it's probably been answered now 100 times, but I'm looking for a sort of beginners guide to installing the OTA on my Evo that has unrEVOked 3.21 on it. I would like to retain root access when completed, but haven't found a definitive guide by anyone who has done the OTA update (9/22 update) over unrEVOked 3.21. I'm gathering that I will essentially need to "unroot" the phone, install the patch, then re-root with 3.21? Could somebody provide a basic guide so I don't end up with a brick, please. If this has already been done, then a link would be more than sufficient, but I can't be the only one out there who is wondering the same thing. Thanks all, and sorry for the nOOb question.
