I got myself a new Nokia 6600 which, according to Nokia, is a Series 60 Symbian phone, and thus according to Apple iSync website, fully supported. However, even after pairing the phone to the Mac, iSync does not decect the phone and thus will not allow syncing. Well here's how to fix it ... I'm assuming Apple with patch it shortly but I couldn't wait!
To do this you will need to be handy with a text editor; I used vi because you need to tinker with files owned by root.
First off, backup the old data! (always a good idea)
% cd /System/Library/SyncServices/SymbianConduit.bundle/Contents/
% tar -cf ~/isync-backup.tar Resources
Now you need to edit some of the files in the Resources directory
% cd Recources
Make an icon for the phone.. I just copied one of the others:
% sudo cp N-Gage.tiff 6600.tiff
Next edit this file: SupportedDevicesInfo
% sudo vi SupportedDevicesInfo
And add the following after the N-Gage details:
<key>6600</key>
<dict>
<key>ATI3Response</key>
<string>Nokia 6600</string>
<key>AgendaDatabasePath</key>
<string>c:\system\data\calendar</string>
<key>AgendaMappingsPath</key>
<string>3650AgendaMappings</string>
<key>ClassId</key>
<string>5243396</string>
<key>MappingsPath</key>
<string>3650mappings</string>
<key>iSyncIniPath</key>
<string>c:\system\iSync.ini</string>
</dict>
Edit SymbianConduit_phones.plist
% sudo vi SymbianConduit_phones.plist
Add this entry:
<key>Nokia--separator--Nokia 6600</key>
<string>symbiantool</string>
All done; start up iSync and add a device. Assuming you have the phone paired, iSync will now find the phone.
