I am using this url to direct my mobile web page to a facebook wall post dialog page, however I can't seem to get display=wap to work.
http://m.facebook.com/dialog/feed?app_id=<myappId>&redirect_uri=<myRedirectUri>&link=<myLink>&display=<wap|touch>&picture=<myPicture>&caption=<myCaption>&description=<myDescription>&name=<myName>
Using display=touch works fine on most devices except some blackberries I've tested, where the dialog page is blank except for the "Publish" and "Cancel" buttons. When I use display=wap, I get "An error has occured" no matter what I do.
Does facebook support this feed dialog with display=wap? I found this url on their developer's web page here: Facebook Dialogs Under the heading labeled : Mobile Display Modes
I'd appreciate any advice!

Currently we don't support the feed dialog in display=wap. Sorry.
