This could make for an interesting script...


Is your tinfoil hat starting to feel the burn? Are you forever aware that the global new world order single government police state are intercepting your phone calls?

Simple, force your phone to 3G only mode (2G encryption has been compromised) and set your n900 to record the locations you are in (GPS) and a list of station IDs. Once you have 'learned' the cell IDs you normally connect to (you always travel around roughly the same area) you set the device to check your database of station IDs against location as you migrate through the network.

A rogue station ID has appeared? MITM ATTACK! They are closing in! Burn your clothes! Acid your fingerprints off! Run for the border!
