Did I alread mentioned the idea to have a capacitor parallel
to the battery? So the Neo1973 cold call the police even without
battery and the simcard and transmitt the coordinates of the phone.
***g*** (of course with black screen...)

Or some messages on the screen from time to time without battery
"I'm stolen - give me to the police"

A question of Thomas Schmidt (wetherfax circuit) "can I then
see where I put my phone...?" brought me to the idea.
First I thought a special call id could activate GPRS and
transmitt the coordinates to the server....
toooo complicated for the most owner.

Text to speach directly on the phone would be nice and with
this menue it would be possible to activate call alarm as well,
when it is somewhere in your flat, but you switched of all sound
and vibra.

So how to come into this meneu by calling your Neo1973?
Not everybody has asterisk gateway to get a special calling ID
to autentificate yor to get this voice menue.

1. You could use a phone of a friend to send a SMS with a onetime code.
2. you using a voice menue for all anonymous caller - so when you
   borrow a phone from a friend, you could switch of the caller nummber
3. calls which are not in your adress book (telephone booth) could be
   delead for 4 seconds before the call is signalisated.
   So calling 2 times in 40 second could switch you to the voice meneu
   "hello this is the voice box of robert..."
When you now type in your special code you could get into your meneu
where you can choose
"Press 0 when you want to aktivate the stolen modus"
"Press 1 when you want to know the coordinates of your phone now"

So a solution without a server would be possible for *every* Neo1973
owner :)
