I've always been wondering: Is there a SIM card configuration flag that allows telling the phone to never even attempt an attach using a given technology?
This would allow leaking identifiers (at the cost of greatly reducing roaming coverage, at the moment), attaching to spoofed networks (for 2G, which does not have mutual authentication) etc.
