The Nokia C6 is a mid-range slider smartphone. The full QWERTY keypad on the C6 is a slide-out keypad, so that it does not take up much space in Nokia's compact form factor when you are not using it. Like other smartphones in this price range, the C6 runs on the Symbian S60 operating system, which comes with audio/video player and 3G connectivity. MP3 ringtones as well as games are downloadable to the C6. The memory of the C6 is 256 MB, which is small compared to similar offerings in the industry, but this can be upgraded by utilizing the phone's microSD card slot (up to 32GB).
