mailto: subject line now supported on the BlackBerry PlayBook

Not sure what update added this, but setting the subject line when using mailto: on the PlayBook is now supported. This is a required feature in order to best use a built in email support feature like I recommended in July. In ActionScript this code would take the following format:

navigateToURL(new URLRequest("mailto:eric@ebscer.com?subject=Pre-populated subject line"))
