Use iphone to connect to Wi-Fi and share connection to USB How to share Wifi connection from iphone to mac?

I would like to know if an Iphone can share its Wi-Fi internet connection over its USB connection.(IE Use the phone as a wifi card for a mac)
No, that is not possible, at least not without jailbreaking or a dedicated app. I do not really know, if apps are allowed to create an network interface over USB.
