Sync Problem: Home iCal Calendar from iMac -> iPhone 3GS via iCloud
I'm unable to sync Home iCal Calendar from iMac (Snow Lion) to iPhone 3GS via iCloud - events appear correctly on iCloud.com but not pushed to iPhone. However Home events created on the phone sync fine in other direction (appearing correctly on iCloud & iCal) - but they can only be amended on the phone.
My other Work iCal Calendar works perfectly in both directions.
Have tried various suggestions to fix but to no avail. Any help appreciated - thanks.
iOS 5.1.1
