Does anyone know of any program in the market that acts like google latitude however it shows you where people are inside places? and not just the area they are in but the exact location of them? thought about this app yesterday when i was walking around the mall after my haircut looking for my wife since she was shopping around while i was getting my haircut. saw friend finder but dont know how accurate/precise that app is. would be nice to have so that she doesnt have to try to listen for her phone to ring or have to stay in one spot at the mall waiting for me.
