You want the equivalent of a tickler file, right? You can do it on the desktop, but not (yet) the iPhone. Make yourself a context mode perspective grouped by start date, sorted as you prefer, available tasks, any flag status, any duration. If there are groups you prefer to ignore, you can close them and save the perspective with the "Restore expansion" box checked so that it will bring it back with those groups closed.
