There is one built in, but it's pretty hidden. Open BlackBerry World, swipe down from the top, and select Scan Barcode. It works on anything. I just tried it on a Wikipedia page that linked to another page.
Or you can download a standalone QR Code reader app from BlackBerry World - I know I've seen at least one, but I'm sure there are others.
