Particularly interesting are the last two questions:

5. What other applications have been rejected for use on the iPhone and for what reasons? Is there a list of prohibited applications or of categories of applications that is provided to potential vendors/developers? If so, is this posted on the iTunes website or otherwise disclosed to consumers?

6. What are the standards for considering and approving iPhone applications? What is the approval process for such applications (timing, reasons for rejection, appeal process, etc.)? What is the percentage of applications that are rejected? What are the major reasons for rejecting an application?
