Quoting from the first post:
"A. Super easy way to figure out if you're rooted.
- <LI itxtvisited="1">Make sure USB Debugging is on.
Menu>Settings>Applications>Development>USB Debugging should be checked <LI itxtvisited="1">Connect your phone using "Charge Only"
- Open a "Run" window and type "c:\evo-recovery\adb-windows shell"

For that to work, you need to have installed the evo-recovery first. No big deal. Just a fly-by observation.
