According to an article on AT&T's website, the SCAMP Database, as of Sept 14, 2005, is comprised of multiple tables, the largest of which holds 743 billion records. Uncompressed, the amount of data stored is 312 terabytes. Today, SCAMP is one of the largest databases on the planet and it operates at near real time (no delay--when you press "send" a record of your phone activity is made that second in the database).
I would just like to point out that if they had compiled 312 terabytes of data by 2005, it's hard to justify the term "relatively new thing". Though I appreciate your reply, it doesn't really answer any of my questions and just makes me feel more concerned about my (lack of ?) personal liberty.
yes, your cell phone provider knows where your cell phone is located anytime it is powered and connecting to a tower. That should come as no surprise. Your telephone records that you get will not be nearly as complete as the SCAMP data.
Talk to your attorney. it sounds like discovery is ongoing, so perhaps he can compel the other side to produce more data
