Exactly. It actually got me thinking if burner phones are already modified (either hardware or firmware) to basically be the man in the middle. There was a big problem with Chinese-supplied hardware in the US gov't which was modified for snooping. My tinfoil senses tell me it would be relatively simple to modify older phones to, for example, send GPS signals even when the battery is not in by adding a smaller hidden power supply that recharges off the main battery when the main battery is in the phone. I guess the only way to be sure is by not using a mobile phone at all.
