[RESOLVED] BlackBerry doesn't open export to Excel properly

[ChetUbetcha]

I have exported an Excel file adn emailed it to a BlackBerry 8820. All it shows is the HTML markup that makes up the tables. It works fine on the desktop, and when I generate an Excel file straight from Excel, it opens fine on the BlackBerry. Any idea why it won't open correctly?

header('Content-Type:application/msexcel');
header('Content-Disposition: attachment; filename=download.xls'); 
header('Pragma: no-cache'); 
header('Expires: 0');

Well, for a start the Content-Type: should be "application/vnd.ms-excel".

Nope, that didn't work either. I even tried making it a simple csv with fields and commas for placeholders, but nothing worked. Back to the drawing board.
