  <p>Can I apply a signature to my app?
  All applications must be digitally signed with a certificate. The default signature applied to your app is a certificate supplied by Amazon that is unique to your developer account. If your signing strategy requires that a different certificate be applied, you may do so by submitting a request via the "Questions about application signatures" subject in the Contact Us section of the Amazon Appstore Developer Portal. Please indicate the title of the application for which you are submitting the request.</p>
