Victor, And if I'm at home with WiFi at home and my laptop plugged into the Internet and plug in the USB (or other tether) to update my contacts list on the phone, because its easier/faster, we have the situation described, even though the intent was not to use the phone as an IP gateway. This gets back to users plugging things in in seemingly arbitrary way that made sense to them at the time for some reason.
