Does anyone know/care to comment on how mobile units convince the Cellular Offices (COs?) they are who they claim to be? The 4-digit "PIN" is fine, but what is to keep me from snooping around for a convenient mobile's ID and using the same numbers for my own call? This seems like a good application for public-key encryption, but I doubt that the world has made so much progress yet.
