For some reason my iPhone stopped syncing correctly with my Macbook. I’d get a message along the lines of “Contacts failed to sync because the sync server failed to sync the iPhone” I’m the type of person who considers it a failure of character to call tech support.

So, after hitting the forums I stumbled across the answer.

1. Open the iSync application.
2. Go to the preferences of iSync.
3. Under the ‘Advanced’ section is a button that says ‘Reset sync history…’
4. Press that button.
5. It may be helpful to restart your computer.

And that should do it – it worked on mine at least.

(Next up a tip that will be handy for anyone who lives in a city with a public transport system)
