I have been using Pages (OSX) since it was first released and love it. I recently purchased it for iOS, primarily so that I could use it to edit articles for publication.
It was simple enough to put the documents on my iPhone through iTunes, but now I'm curious... If I edit a document on my iPhone, how does it save back to the computer? Does this happen automatically when I sync, or is there a manual step I'm missing somewhere? Does it overwrite the document on the computer (thus erasing any changes I may have made on the computer?
