I went live with this site www.sloworkforce.com last Monday. Each scheduled event can have a link for an Agenda and when clicking the link, it will attempt to execute downloadfile.php with a passed filename (uses Open/Save/Cancel dialog). This method works fine for IE, Safari and other desktop browsers but fails on a Blackberry browser. Instead, an error pops up with "Unsupported media type application/octet-stream..." and it attempts to open downloadfile.php instead of executing the php script.

Do I need to add an AddType and AddHandler definition in the .htaccess file for BB devices? If so, what is the format or what am I missing?
