I have absolutely the latest apps and operating system on my iPad and my iMac.
The whole point, I thought, of iCloud's documents sync is that documents should be easily sync'd between Pages, Numbers and Keynote on different platforms.
Pages on the iPad and iPhone store the docments in a "special" folder. In Mac OSX documents can be saved anywhere on the Mac.
I don't know about the "native" file format on the iPhone of iPad, but if I email the document to my Mac, Pages on the Mac can open the file. Its just that I shouldn't have to email it since it's already on iCloud and the Mac has a connection to iCloud.
