This Register article talks about how Palm executives do not feel that the WAP spec will translate well onto PDAs and is more effective on mobile phones. Because of this, Palm has no current plans for a WAP enabled organizer.
This despite the fact that Palm is a member of the WAP forum. Note that this doesn't mean that there will not be WAP software for the Palm, just not "out-of-the-box." There is a already a program program called WAPman that can be used.
