Update OTA , help needed ! ! !

Can i update the OTA on a rooted Evo through Rom manager ?
I'm using the stock Rom Froyo 2.2
Should I update ? Do I need to update ?

If you want to update, download a rooted stock rom and flash. If you already have a stock rooted 2.2, it isn't necessary to flash the new 3.70 release....the new release is just a sprint maintenance upgrade...you really wont see any new functionality.

How do I manually update HTC evo to 2.2

How do I update my evo to 2.2 from 2.1.. ? I need to reroot my evo. I herd 2.3 isnt rootable.. I rooted 2.1 and tried to restore cyanogen mod 7 nandroid back up and it didn't work so I figured I had to be on 2.2 or something. Correct me if I'm wrong

You can update to the latest ota. Then go to revolutionary.io then follow the instructions to root your evo.
This epic reply brought to you by none other than my roxx'd out Evo.
Create a nandroid, install a 2.2 rom, like warm 2.2, and you're good.

Is 2.3.3 rootable?

Returning to complete 6.01.605.05 software stock

I'm trying to return my inc2 to verizon but i dont want to do so until i unroot/stock my phone completely. Is there an RUU for the 6.01.605.05 software yet? Or any other way to return to unrooted stock?
I downgraded mine to stock 5.xx before sending it back.
I essentially downgraded to 2.xx and ran the OTA RUU bringing me to full OTA stock.
