A $15 app by the name of “iTether” lets you have unlimited tethering from your iPhone’s 3G connection to your Mac or Windows computer.
From the App Store description:
Tether is an application that allows your Mac and PC to take advantage of your smartphone’s data plan, providing you access to the Internet on your laptop anywhere there is cellular coverage from your smartphone.
Tether is easy to install, easy to use, works practically anywhere, and is very cost-effective.
There are literally no settings to configure on either the desktop or iPhone. Simply launch the app on the iPhone, connect the iPhone to a Mac/PC, and start using the internet. You can download the companion app for Mac and Windows to get started.
