Anyone thought about this? Sim Cloning your iPhone sim, shaving it down, and using it in an iPad 3G. The device is unlocked, would save you the extra data fees a month. Or at least come with some kind of micro-sim tray for your iphone(like the turbosim devices) so you can swap your sim between your devices. Granted, yes you can tether your ipad to your iPhone with mywi. Any thoughts?
