I have iPad and iPhone with Wi-Fi sync turned on against iTunes on iMac. What takes precedence in defining the content on the iOS devices: iTunes settings for each device, or the selections made on iCloud? In the case of iTunes, both devices show up under "DEVICES", and allow selection of rules of what content has to be sync'ed front the iMac iTunes library. In the case of iCloud, I can select things from iTunes on iOS 5 directly. So, what takes precedence. I am puzzled because the content selection appears to be erratic. I have the suspicion that there are songs that are also duplicated (because they have been purchases from the cloud, as well as present on iTunes).
