When I view the WAP version of the forums on my phone, I can't see any replies to any threads. I can only see the original post of a thread, and I have a box to post a reply.
I'm accessing the forums from the CrackBerry launcher.
In the topright hand corner there should be a list sucb as 'new posts, subscribed and search' type on subscibed and it will show all the threads. However u have to reply to a thread to be able to view it again.
