Instamapper has created an application for the iPhone which allows others to see my location on Google Maps. It does not update my location until I manually tell it to, but the map shows you how old the information is. If you see me stay in one spot for a long time, worry not. I probably just forgot or didn’t feel like updating my location. Also it usually puts the red dot on the nearest roadway, but that doesn’t necessarily mean I am driving down the road. I could be off the road in a parking lot. Additionally, as far as I can tell, the altitude, heading, and speed information are usually not correct.
