It is great fun, and i don't mind sharing at all. but everything is in
dutch and in a real "developer" state.
(lots of files, dirty scripts, you know how it is...)

but the general outline is:

make a script to read all your sms text messages and grep for a cue line
( i use: please call +129876543)
Perhaps my phone is not stolen, but i just lost it. this way people who
find it, will know how to contact me.
restart the script with /etc/apm/resume.d/89checksms-resume, so the
incomming text message will wake the phone and triggers the script.
if the cue line is found, stop the phone from going to sleep (xset
-display :0 s off) and start the gps module.
use gpspipe -r and gpsbabel to translate the nmea track to a gpx track
so you will have normal lat long values.
after the gpx file has sane values, send an sms with those values to a
pre-configured number and look them up at:
i have the script waiting for an hour, and if no gps fix is obtained in
that time i stop the scripts and send a message that it didn't work out.

to read the sms text messages i use the following:

ptsvar=$(dbus-send --system --print-reply --type=method_call
--dest=org.pyneo.muxer /org/pyneo/Muxer
org.freesmartphone.GSM.MUX.AllocChannel string:$identvar | grep string |
awk -F '"' '{ print $2 }')
export MODEM=$ptsvar

chat -s -S -V -v -f  /my/chat/file > "${MODEM}" < "${MODEM}"

and the /my/chat/file contains:

        TIMEOUT 15
        "" "\K\K\K\d+++ATH"
        OK-AT-OK ATZ
        OK ATE0
        ABORT BUSY
        OK AT+CFUN=1
        OK AT+COPS
        OK AT+CMGF=1
        OK AT+CMGL="ALL"
        ABORT OK

Have fun with it and if  you can't make the scripts yourself, i will try
to clean mine up and translate them into english, but please try it
yourself first,
it is fun, it is educational and it is customized for *your* needs.

Kind regards,
