Question: Will MX Player be ported over to iPhone/Blackberry/Windows Phone/Amazon Kindle?
Answer: The developer has no indicated intention of porting MX Player to any of those platforms. Until he says otherwise, this is unlikely to change. The various ecosystems are quite different. Additionally, the developer has said that MX Player works as well as it does because of certain efficiencies and packages found in the Android system that MX uses to its advantage.
