Wonder if this is just the tip of the iceberg or are there other things we aren't being told, say a certain agency hacking people's routers and "accidentally" dumping the entire contents of their HDD for later analysis? The problem is that in combination with lots of borderline techniques like passive phone tracking via SSID and setting up devices via a custom firmware hack to broadcast their location by turning the FM radio chip on and off at regular intervals, its hard *NOT* to be on some database or other.
Contrary to popular belief it is quite feasible to override the lockout that stops the FM working if the antenna is not connected, the range is about 50 feet and I did my own tests that proves even a lowly Nokia el cheapo "burner" can be thusly traced with a flawed SMS disguised as an advertising message. Hint: if the phone battery runs down faster than usual, suspect mischief.
Also having an RF sniffer is very useful if you want to see if your phone is playing shadow games and turning its camera /NFC/etc on at stupid times etc. 13.22 MHz
