Rooting your MT3G is pretty easy. It can be done using an app you install on your phone.
1. Visit universalandroot from your phone and download the universal Androot application
2. Using a file browser (like Astro on the Market) find the apk file and install it.
3. Once installed, find the Universal Androot app in your app drawer. Open the app, let it find your firmware, press the "Root" button and let it take care of the rest!
One last step you may want to do is install busybox. Search the Android Market for "Busybox by Stephen (Stericson)" and install it. Busybox provides commands like copy and paste to the shell (the inner workings) of your OS.
