Am a new ipad owner and want to be able to use it for work. I want to be able to access my docs on pc from ipad and edit and save and synch with pc from ipad. So far I have installed dropbox on both and have purchased quickoffice app for ipad. I can synch from pc to ipad no problem but cant work out how to do the reverse. when i edit in quickoffice I cant see a way to save back to dropbox? Am I missing something? Is there a more efficient way to achieve what I need?
