iPhone to iCal sync issues.

After trying mobile me for the past 2 weeks and giving up with the calendar and address book syncing instantly, not that they weren't working, just didn't need it, I was having trouble with the iPhone calendar not syncing up to iCal. iCal was syncing down to the iPhone however. After trying everything I could think of, such as deleting all calendars, resetting sync history, nothing was working. I also had a lot of deleted calendars showing up in iTunes. Today I found this post:

iphone-to-ical-sync-issues

By running a 1 line terminal command:

/System/Library/Frameworks/SyncServices.framework/Versions/A/Resources/resetsync.pl full

(apple doc)

As far as I can tell it does a full sync history reset. Removed all the deleted calendars didn't actually delete the real files though and allowed syncing again!

Along with this today google have added caldav support for google calendar so now can have proper syncing with ical and google calendar. However I did discover that the iPhone does not add events to that calendar, which is slightly annoying, but can't be helped for the moment. Google just need to add some exchange service to allow over the air syncing and everything will be fine!
