If it has E911 it has a GPS in it. Wether or not you can access it for
other purposes depends on the phones software features. Might I suggest
you read the book. My i560 does allow access to the GPS. E911 enables
the GPS when you call 911 and that can not be disabled. If that worries
you, lookup the non-911 phone numbers for the various public service
dispatchers and program them in the phones memory.

Not necessarily. GSM carriers in the USA are using non-GPS technology for
E911.

The only other way I know of to acquire position then is to triangulate
from various towers. Which only works if one is in range of more than
1. A vector and signal strength from one site is a poor substitute as
it must assume way to much. From what I have read on the topic, E911
(in my handset at least) uses a combination of tower and GPS data. I do
have access to the GPS and can call up a simple log/lat without any
additional software.

CMDA handsets do use a form of GPS (Assisted GPS). GSM handsets do not.
See E-911 in the FAQ below.
