It is using the 3g ability of a phone to create a WiFi hotspot for a Wifi device like a laptop right? what about a WiFi iPad or other tablet? would that work? Also, does verizon offer prepaid tethering? I know that it is something like 20$ a month for 2gb or something, but do they offer a option where you would buy 2gb or so worth of tethering, and then could use it for as long as it took to run out?
