BlackBerry Curve 8330

I currently have the 29.99 blackberry plan through VZW was curious about the tethering and how it works. Can I just hook it up to my laptop and use that as my modem to access the mobile broadband at no extra costs? Any help would be appreciated

Also if anyone was having a problem getting VZ Navigator like I was after an hour with tech support I was able to download it and it is fully functional I can assist.
