caldav stopped syncing - how to fix without losing entries? My family uses caldav in their iPhones to keep a shared calendar (yahoo) in sync with everyone.  One phone, used to add a lot of calendar entries, has stopped syncing. I tried simply reentering the PW to see if that would jump start it, but it is still "stuck".  With no diagnostic information available, I don't have a clue why.   

If I "delete" this shared calendar, I will lose calendar entries added to the phone but not yet at the server.  Any suggestions?  Is there an easy way to select all calendar entries for a calendar and perhaps move them to the "local" calendar, Then I can delete the shared calendar, add it again, then move those new entries back to the shared calendar?  

I wish there were some way to diagnose and fix this, I just don't think Apple has ever provided any tools for that.
Sorry i dont have enough rep to comment instead. However, if you feel lucky and really really need your calendar events, i would try this:


Backup the iPhone using iTunes to your computer, make sure its a Unencrypted backup.
Navigate to ~/Library/Application\ Support/MobileSync/Backup/
Look for the folder updated recently.
Copy that folder to the desktop.
Start quicklooking through some files from the copy on the desktop, you will find some events (one file is one resource, like contact, calendar event, photo etc)
Sort out the events you need, import them to Calendar again by double-clicking on the event (try one first, make sure you have a backup of your calendar as well)


Best of luck, its a tedious job.
