Phone Tracking App
I am a recent iPhone convert (came from the Moto Droid). On my Droid I had an app caled "Droidtracker" where whoever I had setup in a list to allow them permissions, they could send a command via SMS (for example the word "ping") and it would send them an sms response with a link to google maps showing my location. Is there an app like that available for iPhone? I have been seraching the web and all I can find are apps that require a PC component and I don;t want that....
