Find Me by sms is an application in development by xda member adam2022 it can be used to find out anyone’s location via sms. With a simple sms you can get the GPS cordinates or the CellID (tower) information in the absense of GPS. The process can be all hidden i.e. the owner of the cell phone will not be notified. The application can be PIN protected so only those who know the PIN can find out the location.
