With the new iOS4 and supported devices (currently iPhone 4, iPhone 3GS and 3rd gen. iPods), Family Tracker runs in the background at all times, and, unlike previous versions of Family Tracker, user intervention is **NOT** needed for you to track them. Pings are thus no longer necessary. Family Tracker runs at all times, continuously updating the GPS location of the device. Even if the iPhone is rebooted, Family Tracker will automatically resume tracking and updating its position!
