I can think of lots of other ways to implement anti-theft measures in
IMO if I'm too far away from the phone to notice someone nicking it
then I'm unlikely to hear it making an alarm sound.
I would have it instead check http://mywebsite.com/theft.txt and if
it doesn't get a 404 (i.e. you only put the file there when the phone
has been stolen) then have it email you its GPS position.
It briefly occurred to me to have this theft function trigger a
program that periodically switches off the microphone & speaker,
calls 999, and reads out a prerecorded "this phone has been stolen"
message a couple of times. Festival could be used to read out the co-
ordinates to the call operator. However, it would take so few false
alarms - generated by end-users "checking that it works" - to
completely negate the value of this system that it should probably
never be implemented.
