I can't believe people are still confused about this...
So, I'm going to do my best to make it abundantly clear.
IF YOU DO THE FROYO OTA, YOU WILL LOSE ROOT ACCESS FOREVER!
Because it hasn't been released/leaked yet, there is no way of telling how hard it will be to crack it. They may be able to bypass whatever Sprint/HTC does and gain root access again, but it's not guaranteed.
Your best bet, if you want to keep root access is to wait. Usually a day or two after the update, the devs release a rooted version of the same rom. Last OTA took about 16hrs to be released as a rooted version. This one won't take long either.
If you decide to do the OTA because it's such an "amazing opportunity to run the Official FROYO release and I couldn't help myself," don't go crying in the rooting thread later that you want to use Wifi tethering and can't.
On that note, this is still great news. Thanks OP. I look forward to running the rooted version of this sometime next week.
