We haven't verified any of these methods yet (as we don't have access to iPhone 3.0), but word on the street is that iPhone internet connection sharing—aka tethering—is already working on the iPhone 3.0. Our gadget-loving sibling site Gizmodo has a detailed guide to enabling 3G tethering—but they haven't verified it either. According to Mac Rumours, USB tethering is also working. On Tuesday Apple indicated that tethering would be an option in the 3.0 software update, but that it's up to the providers to allow it. So while this really isn't available to the majority of us yet, it's a good sign of things to come. We particularly like the notion of USB tethering, which would likely mean less of a battery drain and better connection.
