This should work well with non JB'ed 3G iphones. I reckon this is called ad-hoc as setoyo stated. Could be tethering too.

"A mobile ad-hoc network (MANET) is a kind of wireless ad-hoc network, and is a self-configuring network of mobile routers (and associated hosts) connected by wireless links"

"Tethering in cellular wireless is the connection of a non-mobile device (e.g. desktop computer, notebook computer, laptop computer), to a mobile device (e.g. cell phone, PDA) for the purpose of wireless Internet access by the non-mobile "tethered" device".

Hope you don't mind. Found this on the net. Hopefully is helpful.

iModem (Windows Only) Now Lets You Tether Over USB Cable.

Tethering your iPhone for internet use can be a real life-saver when there's no Wi-Fi around, but for those who aren't the most tech-savy, the tinkering with proxy settings and the like can be a little too complicated. Thankfully those times may be coming to a close. Unofficial tethering app iModem has just released an update that lets you tether your iPhone via USB cable.
Previous to this, tethering apps used the iPhone's Wi-Fi capabilities to act as a Wi-Fi hotspot that was connected to the cellular data network. The new iModem is the first tethering app to change this. Instead of messing with settings, you can just connect your iPhone to your laptop through USB cable to share internet.
