Figures are now in from IDC for the world phone market in Quarter 3, 2011, showing the market flattening in the USA and Western Europe as saturation sets in. However, the proportion of smartphones in the overall mix continues to rise. Nokia is still king in terms of sheer numbers, selling over a hundred million phones in the quarter, although Samsung is catching up relatively quickly. IDC's stats table is quoted below, though we don't yet have a breakdown of smartphone-only sales.

From IDC's press release:

FRAMINGHAM, Mass. October 27 2011 – The worldwide mobile phone market grew 12.8% year over year in the third quarter of 2011 (3Q11), as smartphone growth declined in key mature markets. According to the International Data Corporation (IDC) Worldwide Mobile Phone Tracker, vendors shipped 393.7 million units in 3Q11 compared to 348.9 million units in the third quarter of 2010. However, the 12.8% growth was higher than IDC's forecast of 9.3% for the quarter and stronger than the 9.8% growth in 2Q11.

It was also the second-lowest growth rate for the overall mobile phone market over the past two years; a reflection of delayed smartphone purchases and conservative consumer spending last quarter. Economically mature regions, such as the United States and Western Europe, were hardest hit as shipment volume to both regions declined on a year-over-year basis.

...However, smartphones drive the overall mobile phone market and will continue to do so in the quarters and years to come.

The smartphone breakdown would have been interesting - I'd be expecting a lull in Symbian sales (waiting for the new Symbian Belle handsets to come on stream and for Anna to roll out for existing devices) and of course there aren't any Nokia Windows Phone sales yet in the data. Samsung's total will have included a small number of Windows Phone smartphones, of course, but it's fair to say that this platform hasn't taken off in a big way yet.
