Just noticed today that my calendar colors are now syncing to my iphone. It used to just assign colors based on the order in which they were synced. It's even syncing colors (i.e. pink) that were not available on the iphone before. I know if you have mobileme it would automatically sync but I don't have a mobile me account. All my software (itunes and iphone) is the latest version. Just wondering if any one else has noticed the same thing.
