Google has launched yet another service that you can use to track where your friends are. Google latitude lets you see where your friends are on a map and find out what they are up to by contacting them via SMS, IM or phone call. This service can work on both your phone and your computer. On your phone’s browser you have to go to google.com/latitude and start using it from there. For supported phones go here. Though this has raised security questions, it will be useful for parents who want to keep track of their kids or just someone who is lost and needs guidance.
