Samsung Electronics Co Ltd has announced a mobile phone which doubles as an MP3 audio storage and playback device, and expects to sell 250,000 of them in Korea this year. The super-slim SPH-M2100 has all the normal mobile handset functions, plus a complete set of MP3 features, including repeated phrase play-back and playback mode set-up. Up to four average length songs or 20 minutes of language tuition can be stored on the device’s built-in 16MB flash memory card, and a 32MB version is slated to arrive in September. The standard battery will allow 11 hours of continuous music playback. Samsung said it expects to begin exporting the device by the end of this year. In April, Samsung launched its Yepp MP3 and FM radio device, with 40MB of memory and a ten-song MP3 storage capacity.
