I think this is what you are looking for- it is an application called EveryWAN Remote and it's free:

Basically it allows you to control your HTC Touch (and others) through your laptop or PC. Its great if you have to do a lot of typing as you can use your computer keyboard and it is also allows you to zoom in so you can see pages better. It is not a tether and you will not get charged.
Cheers!
