While trying to get my Sprint Motorola Razr V3m to sync my Address Book and iCal with my computer, I ran into some problems. Namely, iSync would not see the phone, iSync told me that syncing iCal to the phone was not supported.
My other phone is a Razr V3i, and I was able to sync both Address Book and iCal with it, so I didn’t really believe it wasn’t possible. After searching around the internet for a while, I ran across a solution that worked at whopack. It involves changing a iSync file, so make sure to create a backup of any files before you edit them (just in case).
1) Go to your Bluetooth Preferences (either by clicking on the Bluetooth icon on the top bar or through the System Preferences)
2) Click on the Devices button.
3) If you see your phone listed under the bluetooth devices box, delete it.
4) Navigate to your phone’s bluetooth menu and enter the device history.
5) If you see your computer in the list click options and then click delete. Click back to get to the Bluetooth menu. (Find Me, Handsfree, Device History, Setup)
6) If you have synced your phone previously, open iSync and remove the device.
7) Make sure iSync is closed before preceding.
There are two methods you can use to add iCal functionality to iSync. The first is easier and I recommend it. If the first one doesn’t work though, try the second.
/Applications/iSync.app/Contents/PlugIns/ApplePhoneConduit.syncdevice/Contents/PlugIns /PhoneModelsSync.phoneplugin/Contents/Resources
If the above does not work for you, restore your backup of MetaClasses.plist and open the file (/Applications/iSync.app/Contents/PlugIns/ApplePhoneConduit.syncdevice/Contents/PlugIns /PhoneModelsSync.phoneplugin/Contents/Resources/MetaClasses.plist)in a text editor.
