I need a more reliable system than my (paper) planner + wall calendar. If I add appointments to one or the other, I very occasionally forget to sync the two calendars. Yet I've found certain web-based calendars (YahooMail's calendar, for example) a bit tedious and my current phone does not offer any calendar syncing features that allow me to update and be reminded of appointments when I'm on the go. Does anybody have any specific program and/or phone recommendations? (Ie google calendar with an iphone, outlook with a blackberry etc). I also have found that outlook tends to cause my computer to crash, so I don't use that, either at the moment.
