love this idea . hope it comes out just to some ideas out there. What about say you lost your phone . so you use GPS to track it and you get to the place the GPS says your phone is there. Could it be possible that you send a certain text to set off a alarm. Due to the fact if someone stole your phone they are not just going to say to you that they stole your phone and here it is. So i would bring the cops with me and text the number and my phone will ring an alarm . Guess what you found you baby and take it back home. It just seem to me if somone steals your phone they will not admit that they stoled it until it start to ring from where ever they hid it .
