what Android Version runs on your devices? Android 2.2 brings the built-in feature of Wifi-tethering.

HTC has also a WIFI tethering App, which is called WIFI-Hotspot.

If it is not available on your phone, you can use this app: http://code.google.com/p/android-wifi-tether/ Beforehand you have to root your phone to use this App. This is no problem with unrevoke tool.

On my Dell Streak (running 2.2.2 StreakDroid), I just go to Settings -> Wireless & networks -> Tethering & portable Hotspot ,and then check "portable Wi-fi Hotspot"
