I am looking for a way that I can track a cell phone without having to install anything on the phone. I have tried installing all of those background softwares and turning on the google latitude but my kid always figures it out and turns it off. He is very tech savvy and always knows when I've installed something and how to turn it off or delete it. I need a way to locate him without any installation and I'm not about to pay for this. We go through verizon and I know that you can subscribe to something like this but its ridiculous to pay to keep track of my kid. I know my way around a phone but I'm by no means any sort of programmer. Any suggestions?
