My idea is to have some sort of small gadget that can pair to either the bluetooth or USB tethering of the iPhone and send that out via Wifi so that our iPads can tether off the iPhone. It sounds kinda clunky but not much worse than a MiFi. I basically want this for road trips and visiting relatives who don't have Wifi. Does anyone know if something like this already exists? And no, I don't really care to jb my iPhone. That MyWi app drains the battery so fast! I've read that it even drains the battery while plugged in.
