This may be a dumb question but, mywi 4.0 had an update a couple of days ago that added Bluetooth tethering. Here's the dumb question: Is this addition meant for tethering the iPhone to the iPad? Or is this meant for something else. If not for iPhone/iPad tethering, what is it for (just curious)? If it is meant for iPhone/iPad tethering, how in the hell do you set it up?
