Note: If the steps on this page don't work for you, check out the alternate method of 6133+iSync setup.

I just set up a Nokia 6133 to sync with my Mac over Bluetooth, and the one secret missing ingredient is this file: NOK6133.phoneplugin.zip. Without it, iSync will not allow you to add your phone as a device (and thus, you won't be able to sync the phone with your Mac). I tried this on two different Mac laptops (PowerBook G4, MacBook Pro), and both computers could see the phone, but wouldn't let me add it as a device.

Here's what you need to do to get things working:

1. quit iSync
   
2. create a new directory named "Phones" in your "Library" folder (so you end up with "~/Library/Phones")
   
3. download NOK6133.phoneplugin.zip to your computer, double-click to unzip it
   
4. copy "Nokia 6133.phone" to "Library/Phones"
   
5. restart iSync
   
6. try the "Add Device" stuff through iSync, everything should work this time
   

I didn't spend more than a few minutes digging around and setting this stuff up, and the results are great.
