I think the average internet connection from a device like an iPhone has so much jitter that this approach will not work reasonably well. (try to ping to an internet server and see what kind of jitter you have, it usually is terrible over UMTS, WiFi etc) _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
