I have varying degrees of success when syncing Nokia phones to my Mac. Usually, everything works well as long as you have a phone that’s been out for at least 2 months. However, there was always one issue that wouldn’t go away: all-day events in iCal turned into 00:00-23:59 meetings in Nokia Calendar. These are hardly the same thing. Luckily I found Ali Rantakari’s blog post on just this subject.
