I didn't know until yesterday that Total Commander could do reg edits. But, I couldn't figure out how to do it.

Smeg's PHM suggestion is a program that is loaded on your phone and if you've used the method discussed on this board for unlocking your device, PHM is most likely already on your phone.
There's also a free program that runs on your computer called MobileRegistryEditor if you prefer to use your computer keyboard instead of your phone's keypad. You must be connected (via Active Sync) to use MobileRegistryEditor.
I use both, and they are a little different, but both work great.
