Did Mountain Lion break calendar and note sync between the Mac and iPhone?
When I was running Lion, my calendars and notes synced properly between my Mac and iPhone (with notes going into Mail.app). After upgrading to Mountain Lion, the notes on my Mac were moved into Notes.app and my calendars appeared to be unharmed. I've recently noticed that neither my calendars nor my notes are syncing between my Mac and iPhone.
I use iTunes to sync my data (either via USB or WiFi) and have no interest in moving to iCloud. I have tried the suggestion of enabling iCloud sync on my iPhone, then disabling, as well as telling iTunes to overwrite the calendar data on my iPhone. Neither of these approaches has solved my sync problem.
