Subject: [funsec] Location tracking in cellphones

Hi,

My Verizon Wireless Treo 650 cellphone has an option to
select if location information is sent in for all calls or
only 911 calls.  By the end of this year, the FCC is
requiring all U.S. wireless carriers to provide location
information to emergency operators accurate to about 150 feet
on all 911 calls as part of the Enhanced 911 program
(http://www.fcc.gov/911/enhanced/).

I was a bit surprised to learn that my Treo defaults to
always sending location information.  After a bit of initial
confusion, I got confirmation from both Palm and Verizon
Wireless that my observation about the default was correct.
However, Verizon Wireless told me this is a mistake and going
forward, they plan to change the default to "911 calls only".

I'm curious now when other models of cellphones transmit
location information to carriers.  Can folks on this list
check their phones and phone manuals to see what kind of
controls there are over location information and send me the
results?  I'll also need the make and model of the phone and
the wireless carrier.

For my Treo phone, I found the location option under "Phone
Preferences" in the Options menu of the main phone screen.

Thanks,
Richard M. Smith
