Step-by-Step Video Instructions on how to upgrade your Dash to a very clean and simple HTC Windows Mobile 6 ROM. The official T-Mobile ROM has too many things in it that eventually slows down the device.
I would not recommend this option for people with myFaves because you loose the myFaves application or people who use HotSpot application to find Hotspots. You will also need to go here to configure your device to T-Mobile's network settings:
