>>1369508 (My only issue here, is, how does this now translate to 4G LTE and the soon-to-be 4G LTE-A? What exploit would they use there?)
>>1369524 (Answer, yes. 3G phones have been around for quite some time)
>>1369563 (Again, how does this relate to 4G networks?)
NOTABLE
This is what Q's talking about. Remember the article that discusses how Facebook has a profile for you regardless of whether or not you have a Facebook profile? THIS is how they are doing it.

They are just data mining your phones. I'm fairly certain these manufacturers have a backdoor, even though these devices are supposedly only sending traffic to the towers (encrypted) and then only sent across the carrier's networks (Verizon, Sprint, AT&T, etc.).
There have been network devices that we know send data to China because the hardware is made there. Hell, even home network security systems are NOTORIOUS for this shit. Those little camera systems that people buy to feel safe? They send data back to China in very small increments. China literally has a street view of the world everywhere they are installed.

If these relatively simple devices are doing this, imagine what our cell phones (with all the numerous backdoors we have zero knowledge of) are doing.
