The Nokia 603 was announced earlier this week and its a colourful affordable Symbian smartphone.

Nokia have now released a video previewing the main features of the Nokia 603, which can be viewed above.

The flagship feature of the 603 is that it comes with a choice of 6 changeable back covers , as well as two base colour models Black and White. We're sure this will appeal to teenagers, as well as anyone who values the option to match their mobile to their clothing.

The specification of the Nokia 603 reflects its price of 200 Euros (£175) across Europe. A 3.5 inch Clear back touch-screen is featured, as well as a 1 Ghz processor,  5 mega-pixel camera and 2GB of onboard memory. It runs on Symbian Belle , the latest version of Nokia's operating system.

Once we get news of the exact launch date and what operators will carry the Nokia 603 we'll let you know.
