You are dreaming - those of us who fly our own aircraft know we can frequently get signals at 10 000 feet and call home easily. There is no "buzz" or signal disruption even when the cell phone is right beside the most sophisticated avionics, headsets or communication radios. A repeater in an aircraft connected to a broadband connection such as satellite could easily and safely bring cell phones to aircraft just as it does in hospitals where for years cellphones were banned because they were dangerous. Now whether we want them in aircraft is a different matter altogether.
