Howto get the Nokia N80 to work with iSync
From How2s
Open /Applications/iSync.app/Contents/PlugIns/ApplePhoneConduit.syncdevice/ Contents/PlugIns/PhoneModelsSync.phoneplugin/Contents/Resources/MetaClasses.plist in a text editor and just duplicate the entry for N90. Replace the "N90" strings with "N80-1". Duplicate any of the TIFF files and change the name to NOKN80-1.tiff (Change the image in Photoshop if necessary)
This worked for me:
<key>com.nokia.N80-1</key> <dict> <key>Identification</key> <dict> <key>com.apple.cgmi+cgmm</key> <string>Nokia+Nokia N80-1</string> <key>com.apple.gmi+gmm</key> <string>Nokia+Nokia N80-1</string> </dict> <key>InheritsFrom</key> <array> <string>family.com.nokia.serie60v2.3</string> </array> <key>Services</key> <array> <dict> <key>ServiceName</key> <string>com.apple.model</string> <key>ServiceProperties</key> <dict> <key>ModelIcon</key> <string>NOKN80-1.tiff</string> <key>ModelName</key> <string>N80-1</string> </dict> </dict> </array> </dict>
