I have one unlocked phone and I'm changing between two SIMs (different
providers) and somehow it seems to configure that automagically. I
guess, the configuration is on the SIM. It's like that for all Austrian
providers i tried. So at least here in Austria that should work fine.

well, of course. didn't think of that. how was that with the forest and
the trees? :)

you can pack a lot of information into 160bytes - it doesn't have to be
human-readable - and SMS are almost realtime as long as the provider
doesn't have problems. and if you have an sms-email-gateway somewhere
that solves the problem where to send the data (since your phone is gone).

IMO sms should be the standard-method, because it should always work.

Actually in some contries that might work. :)

That's a really good idea.

Here's the problem: Although it's a good idea that the thief has to use
his own SIM (that's what he expects anyway) but it won't be easy to get
a GPRS-connection for sending the coordinates. If he is using another
provider, the settings will differ. Many providers even demand a
password for opening a data-connection...

The theft-problem _could_ be solved by the providers. They can locate
any cellphone anyway and should be able to give information to the
police, when a cellphone with an IMEI that's reported stolen connects to
their network. But they don't want to!

And a professional thief who is able to change the IMEI somehow will
also be able to reflash the Neo1973...
