Here's another proof of concept that may become easier to accomplish over time. Cre.ations.net posts instructions on how to tether your iPhone -- allowing you to access EDGE internet from your laptop.
The instructions are a bit involved and require some knowledge of using the various hacking tools that give you more direct access to your iPhone. All the needed links/instructions are posted on the tutorial.
Forum user buzzert has posted a video accomplishing the same task (though we don't know if he used the same tutorial). The video demonstrates him browsing MacRumors from his Mac laptop.
