Its my understanding the cell phone coordinates are sent to the cell phone
provider and their equipment reads (and holds) that data. Its not part
of any data available to you in any form unless you talk to the cell
provider and convience them you have a valid need. Highly unlikely in
the US anyway. Even if you could convience them to provide it, they
would likely demaand some sort of out-of-band data transmission facility.
