EVO 4G Gingerbread update now has root via Revolutionary

Revolutionary S-OFF & Recovery tool

Revolutionary is a tool to give you S-OFF on your phone and optionally flash a custom recovery image to your Android phone. A custom recovery image allows you to perform advanced tasks on the system partition, such as flashing custom ROMs and taking a full backup of your phone (a “nandroid” backup). We recommend installing the custom recovery image for all users who want rooted phones.

The current version of Revolutionary, 0.4pre3, is a developer preview. We still haven't made it perfectly easy to use for everyone, but we want power users and developers to be able to get started. If you're not a developer, feel free to try it out anyway; but you'll have to be patient with us while we iron out the wrinkles.

You can download Revolutionary from our site, http://revolutionary.io/.

Windows users, please download and install these HTC fastboot drivers.

Revolutionary comes with NO WARRANTY (express or implied), and NO GUARANTEE OF FITNESS for any particular task. Although we have attempted to minimize the risk the best we can, the authors disclaim any chance of damage to your phone. The entire risk of running Revolutionary lies with you, the user.

I just used this to root my Evo with Gingerbread Update. It works

newbie hoping to root my evo 4g running gingerbread but don't know what version hboot i have. purchased from sprint last year late august. tried the holding down volume and pressing the power button with phone off, doesn't work, just powers up phone. if anyone could help i'd greatly appreciate it.
mahalo,
tina

Make sure you keep holding the volume button down until it fully powers up and goes into bootloader. Sounds like you aren't keeping it down long enough.

Turn off fast boot? That might be his hang up

*EDIT*
Just rooted mine with no issues. Works great but the Beta Key is a bit confusing to read copy and paste into notepad for easier reading.

I had fastboot check and it worked for me.  Just Hold power button down and select Shut off.  Then once its fully off hold the volume up button and power button down at the same time until it boot up.

I searched on google for the answer and found nothing so I'm sure the answer is no.  However I was wondering if an unroot method has been made for this.  I don't want to root and then have something happen to my phone and need to take my phone to Sprint.  My last one the first thing they did was check to see if I had super user then to see if I had s-on or s-off.

Looks like an unroot work around has been made.  I will try this all over the weekend after I read up on how to root with Revolutionary and more on the unroot.
