Tampoc pinten gens bé les coses per poder usar la Blackberry 8100 com a mòdem USB, si ens fixem en les interficies que presenta USB són només de tipus Bulk, quan l’ideal per tal d’usar-la com a mòdem seria que fossin de tipus serial. A més el dispositiu s’identifica clarament com un Mass Storage, o sigui, un dispositiu d’enmagatzematge, o disc extern.
