Sim Free Samsung F400

Another super slider from Samsung but this time a dual slider. Slide the screen down to display a built-in external speaker or upwards to show off the traditional numeric keypad. Concentrating on delivering high quality sound using Bang & Olufsen's renowned ICEamp technology, the Samsung F400's music player not only supports MP3, AAC and WMA audio file formats, but also boasts a music library and music recognition features.
