Ummm, you do know when you're talking into that phone, the conversation goes through the same cell towers as someone using the latest iPhone, right?
Even shithole 3rd world middle eastern countries have the technology to track all communications within its borders, so you can be guaranteed the US has far superior technology.
Yes, I realize that if they wanted access to my texts, calls, etc..., they could tap into stored data.
But my shitty phones don't have built-in GPS systems or video cameras that can be remotely activated.
