Unless you actually created the phone itself, all you are doing is putting a Sim card in it, and calling it a BurnerPhone. No offense, but I can't just buy an iPhone, put a Sim card in it, and call it the YoPhone.... Can you clear up the fact that you make the phone or you buy it yourself in bulk?

All phones have a unique identifier that is sent along with the SIM identification. Fairly easy to connect your "anonymous" SIM with any others you've used.
