Why can't they just make it like WMWiFi Router for Windows Mobile? It turns the phone into a WiFi modem and your laptop just automatically connects to it.
This is essentially what it does. A lot of people here are making it seem like more trouble than it actually is.
1. Download PdaNet through Cydia.
2. Create an ad-hoc network on Vista. click Start > Network (right hand side of the start bar) > click Network and Sharing tab on the top > click set up a connection or network.
3. Choose wireless ad-hoc for your new network. Leave encryption to "none", unless you want to set up a WEP, and give your network a simple name like "iPhone Tether".
4. Vista will notify you that it is finished and waiting for something to connect to your new network.
5. Fire up PdaNet. Make sure Wireless Router option at the bottom is set to "On." It'll check to make sure you have access to your cellular data network. Once it confirms this, exit out of PdaNet.
6. On your iPhone, go to Settings > Wifi > connect to your ad-hoc network, "iPhone Tether" (or whatever it is you named it).
7. Fire up PdaNet again, and it will automactically connect your computer to the internet. You're done. You can exit PdaNet and have it run in the background as long as you don't turn the wireless router option to OFF, enabling you to lock and turn off the screen, thus saving the battery (which you can also keep fully charged this way).
In reality, all of these steps take less than 2 minutes for anyone who knows what they're doing...and after you save these wireless settings on the computer, it's just a matter of seconds to get it working after that first time you set it up. If not, some people who don't know what they're doing are better off using mobile safari on their iPhone...
