I just upgraded to Kies version 126.96.36.19981_4. This version makes Sync with Address book operative. Some successful improvement! Well done to Samsung development team! However, Sync schedules with iCal is still inoperative. The Syncing schedules with iCal has always been cancelled in half way of syncing. The sync took quiet long time - probably some issue and at the end they system cancels the operation. Samsung development team seems not as good as Windows platform support. They are still staying in version 1 while Windows has issued a number of upgrades for version 2. Work harder to compete with Windows!
