Can some one tell me if I need a blackberry data plan or if a media.net plan will work for telenav on the Cingular/At&t network. My bad if this has already been answered but I could not find it.

You need a Blackberry data plan. It uses the data plan to access maps at telenav.

^^Ditto. The Media.net plan won't work for Telenav.

Thanks!
