Have you tried the Docs to Go? That seems to be the only application that has support for Microsoft documents on the Blackberry or at least the only peice of software that I know about.
I had docs to go, but deleted it because it seemed useless. it's funny because we don't get a manual for these apps like other items we buy..trial and error method.
Maybe I need a different version? Thanks.
