Eye on Thief watches SIM card to protect phone

Want to protect that pricey smartphone from theft? You could carve out a cheap phone and turn it into a decoy Bluetooth headset, hiding the real phone in your bag. Or you could install Eye on Thief, a $7.99 program that monitors your phone's SIM card, and phones home if the card has been switched. Of course, this will only work if the thief doesn't wipe the phone's memory before swapping the card, but as far as insurance policies go, this one's a real bargain.
