I found a link recently to an article about using your cell phone with your laptop (or desktop PC in a pinch) to get on the Internet. Maybe you're traveling and you can't find a Wi-Fi hotspot nearby, or you don't want to pay extra for Wi-Fi access somewhere, or maybe you can't afford to drop the money on a new wireless broadband card and services fees for your laptop.
If this sounds like you, then check out this article: How-To Roundup: Modem Tethering. Scroll to the bottom to select your phone type and download the appropriate software for free. (Note that you need to have a data plan with your cell service provider.)
The instructions worked out great for me and my Motorola V3m phone...
