According to Gartner, worldwide smartphone sales reached its lowest growth rate with 11.5% increase in 3rd quarter of 2008. It also says that Nokia is the #1 smartphone manufacturer/seller:

Worldwide smartphone sales to end-users totalled 36.5 million units in the third quarter of 2008, an 11.5 per cent increase from the same period in 2007.
:

Nokia maintained its No. 1 position with 42.4 per cent market share in the third quarter of 2008, but for the first time it recorded a decline in sales of 3 per cent year-on-year (see Table 1). “Nokia is feeling the pressure from increased competition in the consumer smartphone market,” said Ms Cozza.

I believe Nokia’s lack of touchscreen handset that competed with the iPhone and Android (and others) really harmed them in 2008, and that releasing a touch-based handset in 2009 should be a top priority for Nokia.
