Answer : Unable to view sharepoint sites from PDA

Well that's the solution Microsoft are suggesting. I have done some research for you and I cannot find any browser based solution to this. There is some chatter on various Blackberry forums where they have implemented the solution Microsoft suggest and it works for them.
