For example, what does it mean to upload new photos to icloud for the photo streaming feature on the iphone, but not in iphone when icloud is the new facet for iphone. There's a folder for photos for iphone so it must mean that the upload is sent to iphone right? But how can you tell theses photos be "property" of icloud exclusively when you do not know how it works and it doesn't have a folder intrisically?
