Found this tracking device literally in the middle of the road. Housing was a bit beaten up, circuitry looks fine. SIM installed, UART at the bottom, USB test points on the left, 2x microphone, BT, WiFi, and GSM antennas. Yes, I've disconnected the battery (it was dead).

At the time, there were few legitimate career paths for hackers. We thought it would be amazing to do what we loved and actually get paid for it. It worked for a while, but the hard lessons of business and friendship still haunt me to this day...
