"What it purports to do is allow you to lock down a missing phone via SMS message and trigger it to begin broadcasting an alarm (which will continue to resume each time the phone is turned on until you deactivate it), and if the phone is really missing you can actually 'vacuum' all your important data (data which you might not have been sharp enough to have previously backed up) to another application on a PC or another phone so that in the end all you might be out is the cost of the phone itself which is now rubbish in the hands of the thief.
In fact, so smart is this application that should the criminal who had the temerity to take your handset attempt to unlock it and insert another SIM it will promptly call a designated third number (of one of your friends - you choose this in advance) with the number of the new GSM card that has been inserted into the phone. This allows you to ID the phone and to report the incident to the authorities."
