Smscon is a n900 complete control utility by sending sms messages to it. This is handy in case you can't find your phone (it's lost or stolen).

Smscon is a two part Python script running in CLI; smscon & smscon_daemon. Smscon is the CLI control part and smscon_daemon is the "running in the background" part.

Smscon can:

• autoload at boot;
  when device reboots it loads smscon_daemon in the background.
• creates a log file (on the device)
• detect SIM card change and sends new phonenumber and IMSI code (return SMS) to other known mobile number;
  if somebody has stolen your phone and put his/hers own SIM card in it.
• send current GPS location coordinates (return SMS).
• reboot the phone;
  only works if your SIM hasn't a lock code.
• shutdown the phone.
• open a reverse ssh connection to your own server (WLAN/GPRS connection);
  control the device at CLI level from you own home.
• ftp a frontcam picture to your own server (WLAN/GPRS connection);
  to see where your phone is or who is using it.
• send the current remaining battery charge (return SMS).

Future ideas:
- record audio (with phone mic) and ftp the file to your own server (WLAN/GPRS connection).

Smscon is triggered by an SMS message with a predefined known command and then will execute the task in the background.

If so it will send a reply SMS with the information.
