However, the introduction of iCloud finally broke iSync, too. You will not be able to sync a Nokia phone with iSync if you have iCloud activated.
The solution is:
- Create a new user (called for example NokiaSync)
- Select all Address Book entries. Drag the list of entries to your desktop. This creates a .vcf file.
- Copy this file to the Desktop of your new user NokiaSync (via the NokiaSync user's Public folder, or some other means).
- Drag the .vcf file into this user's Address Book.
- Launch iSync for user NokiaSync and sync NokiaSync's address book with your Nokia phone.
If you add new entries on your Nokia's address book, you can do the opposite process and Mac OS X will reliably detect which new entries were added and will copy these to your regular user's Address Book.
[kirkmc adds: I don't have a Nokia phone to test this, but it makes sense. It seems like a lot of work to update a contact list.]
