What you would want to do is go into the settings on your iPhone, and turn on the personal hotspot. You can set the wireless settings there to start broadcasting. Then you can get a Netgear USB adapter or something like that to connect to the wireless networks in your area. Your iPhone should show up there now since you basically just turned it into a wireless router, and you can connect to it that way. There may be a way to do it directly connecting the phone to the computer, but I've not tried it so I can't say for sure either way. You may need to check with your carrier to make sure that you can do this though, I know some companies like AT&T charge extra, or require you to have a bigger data plan to do this now.
