You should create and use a mutable array of previous locations that were updated from previous calls to "locationManager: didUpdateLocations:".
According to the Apple documentation, the only time that "locations" array passed in via the delegate method will have more than one entry will be "If update events were deferred or if multiple events arrived before they could be delivered, the array may contain additional entries."
