Hi, I have writen two applications (in Python) which will be used as a anti-theft solution for my N900.

The 1st is an application in the background which looks at sms messages my phone receives and if there is a specific command in it from a specific sender it will start the other Python application in the background which is sending the GPS coordinates, through gprs connection, to my website where the data is processed to a log file. The GPS data is then on my website, in combination with Google Maps, processed to nice pictures with the current tracking path of my 'stolen' N900. This made my N900 a moblie GPS tracker... It works great!

This is why the N900 is so great, a little mix of Python, Apache webserver, html coding & Google Maps makes it all possible...

It's also possible to send other information this way; battery life, movement (accelero meters), webcam picture etc.
