Samsung's previous partnerships with high-end audio company Bang & Olufsen has resulted in two rather expensive team ups - the Serene and Serenata.

Presumably with the aim of putting B&O's sound quality in a more affordable device, Samsung has launched the F400 at the Mobile World Congress event.

A 900/1800/1900/2100MHz 3.6Mbps HSDPA with UMTS and EDGE handset measuring 103 x 48 x 16.9mm, the phone has a music focus.

A dual slider, when slid down, speakers that feature Bang & Olufsen's ICEamp technology are revealed. Also on the music front there is an FM radio with RDS, and music library and recognition software.

Elsewhere there's a 3-megapixel CMOS camera, a 2.2-inch TFT 240 x 320 resolution LCD screen and Bluetooth and USB 2.0.

Pricing, availability, etc., all to be confirmed.
