He doesn't want to install a ROM.. You posted what you were running but thats not what he's interested in.
Download z4root, unzip, place in the root of your SD Card.
Download Astro File Manager, navagate to that z4root.apk file, tap it, hit App Manager and install it.
Once installed open your App list and run the program and root your phone.
Afterwards you should head to the market and pick up a app called Droid X Bootstrapper, or get it from an alternative source, your choice.
Once installed open Bootstrapper, hit Bootstrap Recovery, then Reboot Recovery.
Boom, your in Clockwork Mod. Now using the volume up and down keys go to Backups and Restore, then the camera button to select. You'll see 3 options. Use the volume keys to go down to Backup, hit your camera button and let that process run until its complete.
When its done hit the Power/Lock button and wait till it brings you back to the main menu and using your camera button select Reboot.
Then go to market for Wireless Tether and your done!
Hope this helpful. Cheers!
