I think it's that gimmicky thing where it has a app that shows you a radar like view with the cell numbers of cellphones near you. (Might just show the a blip or something).
Actually its pretty cool. When u get the phone u setup two numbers of either ur friends or family and if someone steals ur phone once they put any sim card in ur phone the phone automatically sends an sms to the two numbers u setup giving them the cell number of the criminal plus ur imei number
