Hello MacRumors, When I sync my iPhone 4S from iTunes, it won't update the changes I've made to the calendar on my iMac. For instance, deleted events still appear in the calendar app on my iPhone. I've gone through the syncing options, but I'm absolutely clueless to what causes the malfunction. I just sync between my computer and the iPhone. I haven't enabled any web accounts, like Google Cal oder iCloud. All the desired calendars are checked in iTunes. I've even tried the to "replace information on this iPhone" function, which should have resolved the issue, but didn't. Both calendars should always be the same, since I write most entries on the go. However, I prefer to do bigger edits in OS X, with a real keyboard. Any ideas?
