I was talking more about content of the phone: emails, passwords, pictures, contact lists... But proper OSS phone could give answer to GSM location as well. Imagine network similar to Tor, where SIM would be emulated on phone and shared among community members. Phone would automatically rotate SIM and network IDs every hour. The actual voice call would be over encrypted VOIP. I am not saying it would be practical (or even legal), but OSS could solve technical part of it.
