Nokia C3-01 iSync Plugin
My only complaint is the phone icon that appears in iSync has a white background and the image of the phone is small. I found a high resolution image and created a new image for the plugin which is available for download.
When you get it replace the image
~/Library/PhonePlugins/Isync Plugin C301.phoneplugin/Contents/Resources/com.nokia.c301.tiff with my version.
