Yup, from DF tweet ultraflix 3.0 with sub4mbpd debuted with GI Joe Retaliation, so streaming GI Joe with a mobile is possible. The rest of the uploaded movies will have to be reencoded with the ultraflix version 3.0 to have the same benefits. I think that's also one of the reasons of the delay of upload of movies on ultraflix besides the HDR enhancement and signatures from producers.
