Unfortunately, I wasn't paying much attention. When I saw I had a text message, all I remember doing is clicking on it. It took a while to open (I was wondering why) and then I noticed mappero had started. I thought at first I had somehow clicked it. Mappero showed the real time position of the delivery guy - he/she was in a building across the street at the time I received the text message. I had tracking on and it continuously updated and typically showed a speed of a couple of miles per hour. When I go to my Amazon account and look at the order now, it only indicates "text tracer" or something like that. I could swear that originally it said something like "mobile tracer." It already had my N900 phone number entered - all I did was click to enable. This same option showed up a few days earlier on another order but I had not enabled it. I'm wondering if mappero was receiving info via the Internet (although the gps symbol showed that gps was on).
