LocationShare is a simple way to tell someone exactly where you are. This can be simply done by opening the application and waiting for your iPhone to get your location. Send your location by E-mail of SMS. This is received by the person you send the message to and as long as they have LocationShare installed on their iPhone, it will open the application, they click on 'Show Map', and they will see their current location and your location.
||Compatible with iPhone 3G, iPhone 3Gs, iPhone 4. iTunes account required.
