For example lets say I tether my iPhone to my iPad and use a app over 3G/4G on my iPad that uses the 3G/4G will 3G Unrestrictor work? Of course I will only be able to install 3G Unrestrictor on my iPhone at least I believe. I haven't bought it yet. Whenever I go to my iPad to buy it it says not supported of course because it is only a Wifi iPad.
