How do I turn the Cellular Data popup off? I don't subscribe to Verizon (iPad Designation), so don't appreciate the frequent notification that my iPad 2 can't make the connection. My "Settings/Cellular Data" is already set to Off. The goal, by having it set to off, is to prevent the IPad from using this function all the time. Anything to lessen the draw on the battery. Obviously this didn't work, so is there another way to stop the popup screen?
