OkieGranny I've got an honest question that I hope you or some of the other posters can answer. I don't know the answer, and I wish that I did.
I've noticed that there seems to be somewhat of a consensus that the Jamison's Blackberry was continuously tracking the Jamison's location up to the point where they left it in their truck and that LE probably has all of this detailed information for days of travel. Maybe I'm over-thinking this, and after we have seen what the NSA can do I shouldn't be surprised, but it doesn't make complete sense to me. I don't even own a Blackberry or smartphone so any of you with a Blackberry please set me straight.
There is no doubt in my mind that almost any cell phone has a gps chip that can obtain the instantaneous lat/long upon request at any time. I understand that certain applications can request a reading such as a call to 911, or the taking of a picture where the lat/long can be included in the meta data of the picture, or Big Brother might even hack into your phone to get lat/long readings. There are also special software applications for the phones that make nearly continuous requests for lat/long readings and record them in a track log and subsequently share that log with others. I'm just having trouble with the notion that by default a Blackberry is continuously recording lat/long data and writing it to a file. I have more than one hand held gps designed for hiking and outdoor navigation. It is capable of creating a tracklog of the entire trail, but it is limited to 10,000 trackpoints and it consumes the batteries faster when maintaining a log. Why would a cell phone do this all the time at the expense of battery life? Does a Blackberry have a command or menu selection to dump this log to a printer or email? Does anyone have actual knowledge of a tracklog being extracted from a plain jane Blackberry without special track logging software?
If Blackberrys and Smartphones are creating continuous track logs by default, I'll never be buying one.
