Open Safari in your iPhone and go to http://www.eduzapps.com

Add the page to your bookmarks and name it "SaveMyDocs"

Edit the bookmark you just created and change the address to: javascript:window.location.href='saveme://'+window.location.href;

Now you can open any document with Safari, and if you like to save it just open the SaveMyDocs bookmark, it will open the application and start saving it automatically.
