I need a mobile application that allows me to control a mobile symbian device. I rent devices and i want to be able to turn them off when the rental period is over.
In essence the app is supposed to:
1) Run in background
2) Receive one command (e.g. CHANGEPIN//OLD=1234//NEW=2345) via SMS and change SIM CARD's PIN
3) Receive one command (e.g. LOCKPHONE//OLD=243434//NEW=545454) via SMS and lock phone hardware
4) Protect itsself as much as possible from being uninstalled and from harware reset
The application should run on as many devices as possible (NOKIA and non-NOKIA). In your bid, please specify which devices you think your app could run on.
