OS X 10.4.6′s iSync Natively Syncs to S60 Devices
Killer.
The new iSync natively supports the Nokia N90, so I am not using the PhonePlugin that I found for it in order to sync.
Additionally, it now natively supports the Nokia S60 sync application, so it probably doesn’t need the iSync application installed and running anymore on the device. Syncs are faster and they appear to also be more reliable. I also like that since it is using the standard sync services from Nokia, you can actually see the status of your sync on the device.
