A first mobile device requests a second mobile device to navigate to a destination communicated to the second mobile device by the first mobile device, wherein at least the second mobile device, if not both the first and the second mobile devices, is GPS enabled and is capable of navigation. In one scenario, a first user of the first mobile device requests the second device (or the user of the second device) to send a notification when the second user has reached a certain destination or is in the vicinity of a certain location where the first user and the first mobile device are currently located. |
