I reported the problem with my S-E T610 and iSync. Sync operations were successful, but grew ever longer and reported ever more changes. Finally lasting well over an hour and reporting over 25,000 changes. After the new versions of iCal and iSync were installed it did maybe 3 long syncs, them somehow fixed itself and now a sync takes about 2-3 minutes. My suspicion is that iCal had a corrupted database that the new version was able to repair. -Joel
