The iPhone 4S, which was released in October, made up a quarter of all handset sales in the four weeks before December 9, according to market research firm GfK, closely followed by Samsung’s Galaxy SII which was the second-best selling phone in the week up to December 9th.

However, a big disappointment for  Nokia’s new Lumia handset which got off to a poor start, failing to make the top 10 handsets in the four weeks of the survey period. The Lumia, which runs Microsoft’s Windows Phone 7 operating system, was released in Britain on November 16. The iPhone 4S is a more powerful version of its predecessor, with an improved camera and a new voice control system called Siri. Last week, there was speculation that Google was working on its own voice control software to be released as part of its Android mobile operating system.

Not such good news for RIM, the Canadian company that makes BlackBerry handsets, it has had a bad year but there was at least some comfort in the GfK data. Sales of BlackBerry handsets increased during the period of the survey, with three variants of the BlackBerry Curve in the top 10.
