I'd like a theft alert kind of application to be developed for the iPhone. It should work like this:
The application should be capable of reading the IMSI number of the SIM card.
Users should add their own SIM cards which gets stored in the database. Whenever the iphone is booted, it should cross-check the current IMSI with the list of IMSI stored already as own SIM and if a new IMSI is found, an SMS alert is sent to all numbers defined by the user.
Additionally, it should make use of the GPS and send the location co-ordinates back by intercepting specilly coded SMS.
