Torch :: Blackberry Registration Won't Register

I have recently installed the latest update on my torch, and when the process has been completed I can't access any of my email accounts or several other apps i.e. fb, twitter, rss feeds, etc.I have looked through the forums and followed the steps of registering through the mobile site, but none of these methods have worked, as an error message always appears.I have also found whilst running the diagnostic that the 'blackberry registration' field is 'no'. I have tried to register the devise using the host routing table method, but this isn't giving me any results!
