I am by no stretch of the imagination a Mac expert, but I think I have found the solution to the sync problem.
I was having problems syncing only my contacts (all 2500 of them). It would either hang up syncing or tell me that the sync server failed to sync the iPhone.
I contacted Apple Tech Support this am and the tech I was talking to acted like this was the first time that he had heard of this problem. We tried trashing preference (plist) files and cache files, but no luck. I had completed a complete restore and restart of my computer and still no luck. We basically ran out of options and he stated he would open a trouble case on it.
Well, my curiosity got the best of me and I started farting around with iSync. In the preferences of iSync is a checkbox which either allows or disallows applications to sync with each other. I unchecked it, closed iSync and opened iTunes.
I put my iPhone in the Dock and when it came up on iTunes, under the "Info" tab, all of the checkboxes were checked, but there was NO information to be synced.
I then unmounted my iPhone and closed iTunes. I opened iSync again and rechecked the checkbox to allow syncing between applications. I also pressed the "Reset Sync History".
I then closed iSync, reopened iTunes and re-docked my iPhone. I then checked under "Info" and the information was back. I then tried to sync my contacts and it worked perfectly.
I hope that this helps everyone with this problem.
