It's working, after a bit of playing with.
1. Download the iSync Plugin from Mactomster.
2. Copy mactomster.phoneplugin to the /Applications/iSync.app/Contents/Plugins/ApplePhoneConduit.syncdevice/Contents/Plugins directory.
3. Open up the MetaClasses.plist file inside mactomster.phoneplugin/Contents/Resources with the Property List Editor.
4. Scroll down to the entry for com.nokia.E61 and copy (or rename) it to com.nokia.E62. A few small changes need to be made for this to work with the E62.
Identification.com.apple.cgmi+cgmm: Nokia+Nokia E62
Services.0.ServiceProperties.ModelName: E62
6. Open the Bluetooth Preferences Pane in Systems Preferences.
7. Go through the process of setting up a new device. If you need help with this, look in my blog archives for the entry on setting up a Motorola V600 with T-Mobile.
8. Start iSync, go to Devices > Add New Device.
9. Select the E62.
10. Sync
