<p><br /> Finnish giant Nokia has unveiled an arsenal of smartphones at London's ExCel centre at its annual showcase conference.<br /> </p><p><br /> This comes hot on the heels of a change in top management, announced last week. Neither outgoing Chief Executive Olli-Pekka Kallasvuo nor incoming CEO Stephen Elop attended the event.<br /> </p><p><br /> But Nokia still presented a strong front, hitting back at competitors Apple and Research in Motion by launching new phones with large touchscreens.<br /> </p><p><br /> "For today it's all about here, and now. It's about three words. Nokia is back," said Nokia's Executive Vice President for Markets, Niklas Savander.<br /> </p><p><br /> Nokia still controls around 40 per cent of the global smartphone market, but has lost out in the fatter-margin market for the most expensive phones.<br /> </p><p><br /> The new smartphones E7, C7 and new version of the C6 - in addition to the N8 that was previously announced - will go on sale before the end of the year.<br /> </p>
