Hi everyone... I want to delete webmessenger but I can't find it on my blackberry. (options, advance option, application) and I don't see it on my desktop manager either.. how do i get rid of it?

Also one more thing.. how come when I try to install a new application using my desktop manager..like for example i just installed verichat using my desktop manager and i wanted to install dopewars but then it says verichat is unknown module or something so it has to delete verichat before installing dopewars. How do i fix this? Thanks guys in advance.
