I have no idea if this is possible or if it already exists but is there an app that allows you to locate your phone using another Droid via GPS? In my vision, my sister would be able to download the app to her droid, and then if I lose my phone, I'd be able to enter a pin number or something in the app on her phone which would then show where my phone is on her GPS.
I think it should be possible since if I wanted to I think I could set it up like that anyway (what is that called again, where your friends can GPS you all the time?) but it's not something I want active on a regular basis, which is why there would be a PIN number involved or something along those lines.
I realize the phone would have to be on (I think?) and GPS would have to be enabled, but I think something like this would be extremely handy, especially considering how much the phone cost and how much information is on it. It could really save your ass if you catch the loss quick enough (before the battery dies).
Does any of this make sense?
