UPDATED 25 October 2011
I love iCloud, Apple's new way of sharing information, documents and photos wirelessly across Macs, iPhones and iPads. But when I started using it, I was frustrated to find it copied one of the worst flaws of MobileMe - duplicated calendar entries.
A quick Google search suggested various ways of solving the problem. But I found a very simple solution myself.
On an iPhone or iPad, open Calendar, and open the Calendars tab on the top left. I had 'All from my Mac' ticked as well 'as All iCloud'. Unticking All from My Mac got rid of the duplicates.
I'm now on iCloud 9!
UPDATE, 25 October
Sadly, things didn't prove quite as simple. Everything's fine on the iPhone. But on my iPad I've now got the problem Frank describes in the first comment: clicking between calendars doesn't get rid of the duplicates. Bizarrely, I now have duplicate entries of recurring calendar items. But they're not identical: they're copies of the earliest entry, duplicated for every subsequent entry.I've got duplicates of a stack of old entries on iCal on my Mac - but I can't see any way of selecting any calendar other than iCloud in iCal.
Apple, this is a total shambles.
