Help. I have spent 4 hours and a trip to the Apple store and Verizon store.
I have a Tour for 2 years. Synching to iMAC for two years without problems. Calendar was iCal. A few days ago, Apple had an automatic update for MobileMe. Unfortunately, I said "Yes." Now Tour won't sync iCal calendar. Verizon is clueless. Apple guy said something about installing CalDav on my phone, but no one knows how to do this.
I have uninstalled Blackberry Desktop Software, and reinstalled. Same thing happens. My phone is useless if I can't sync a calendar. I'm furious and tired. Apple says it's a Blackberry problem, Verizon says it's Apple and Blackberry, and Blackberry charges $50 to answer the phone.
