using phone as a modem to connect to internet?

I have a my touch 3G slide and I have been trying to figure out how to use my phone as a modem so I can hook up my laptop to the internet. I have tried the proxoid app and easy tether, but cannot figure out how to use them/install drivers. Can someone please help.
How about Android's built-in hotspot feature (in Settings > Wireless and Network Settings > Settings for Portable WiFi hotspot > Configure WiFi Hotspot)? Nothing to install. It's already there!


I down loaded pdanet works great for me. I use the ENABLE BLUETOOTH DUN you need to sync the computer with your phone first. put the phone and computer in discoverable mode if you want to do this wireless
