Samsung presented a mobilephone called Samsung juke (U470), which incorporates all functions of a mobile phone and a player mp3.
His screen turns totally 180 degrees when needed using either the keyboard to send SMS or talk on the phone, but if you use it to listen to music, you do not need to open it, because it incorporates a button in the form of a wheel, with which you can perfectly manipulate the reproductive performance of audio files.
This model is very convenient to keep in the pocket of the trousers, in the backpack, and even in the liner bag and its design is very elegant.
The factory will have an internal memory of 2GB for playback MP3 and WMA, VGA camera with nightshot and support for Bluetooth stereo headphones. For now, only Verizon will be available at least for one year, so you know you need to be with that company if you want one like this.
