I came across this application to view the WAP pages.
NMIT is a content authoring tool that supports the creation of Mobile Internet content like XHTML, WAP, and MMS (including SMIL transitions and timeline). Content can be previewed on supported SDKs. DRM protection can be applied to such content.
Download this application here http://www.forum.nokia.com/info/sw.nokia.com/id/f156b8e9-1dcd-4e5b-8e75-6e6ceded398e/NMIT_41.zip.html
I've tried to download but it is restricted to forum members only. I'll download later, lah...
Anyway there's another online viewer for WAP from w3schools.com... But it seems like an old version to me.
