At&t subscriber from Durham, NC. I was really shocked when I find out that one of my friend always knew where I was present even when I didn’t diverge the details to her but later i found that it was the technology to track a cell phone. I couldn’t gather the confidence to ask her about it but am really curious to make use of it at the earliest. So is there someone who got good information on how this technology works and the different ways to access this service. Waiting eagerly for your response guys……
