So my update to 3.0 went off without a hitch. But now when I sync I get a Sync Alert that says: "Syncing with iPhone will change more than 5% of your Calendars on this computer." Looking under information details it appears the changes are all in people's birthdays. Perhaps there is a new way the iPhone catalogs them. For example, it says: BEFORE: Modified recurrence: repeating every year , recurrence never ends URL: addressbook://64A5BD72-A99D-B4...:ABPerson AFTER: Modified recurrence: repeating every year , recurrence never ends URL: <empty> This is how 38 changes have been alerted in Sync Alert. Is this an iCal issue or an Address Book issue and how did iPhone 3.0 cause this. Is anyone else effected?!
