iCal events entered on iPhone disappear
I have an iPhone 4 running version 6.0.1. My desktop computer is an iMac running 10.6.8, and I have no desire whatsoever to upgrade the OS.
I charge and sync the phone to the desktop, and events from the calendars used to sync just fine. Now I am finding that some events I first entered on my phone disappear from both the phone and desktop iCal. I haven't been watchful enough to know if the event ever appears on the desktop calendar. Also, some events are doubling up.
On the desktop, I have iTunes 11.0.1 and iCal 4.0.4. I have an iCloud account but that calendar is totally empty except for recurring events long ago deleted.
I have looked through requests like mine, but am having trouble following.
Help! I'm having to wonder if I'm supposed to be somewhere else.
Thanks!
