Hello, I am new to the iPhone community and I just discovered Google Latitude. I am a bit confused as to how Latitude is supposed to function however. I created the Latitude bookmark (for the Home screen) on both my iPhone and a family member's iPhone. Now, if I go to the Latitude page on my iPhone, I am not able to see my family member's location on the map even though her iPhone is on. Her location displayed is the one from several hours prior when she was using Latitude. Would she need to also activate Latitude on her iPhone at the same time? If so, this would seem to indicate that live updates could only occur if both Latitude apps are active at the same time. Thank you for the clarification.
