Samsung has been showing off its ultra-slim Ultra Edition 5.9 phone at every opportunity it gets, but the 5.9mm-thick - don't ever put it your back pocket - handset has finally gone on sale, in the firm's native Korea.

Samsung reckons the phone, more prosaically known as the SCH-C210 in Korea, is the thinnest in the world. Maybe, but what we can say with certainty is that the skinny phone incorporates a two-megapixel camera, Bluetooth and MP3 playback into its all-black casing. There's no official word yet on when the 5.9 will appear on our shores.
