The smartphone OS wars continue to rage, with new kids on the block upping their game to further erode the market share of their longer-toothed rivals.
Apple's iPhone OS and Google's Android open mobile platform grew the most last year, according to analyst house Gartner, with number-one smartphone OS Symbian shrinking further.
Symbian lost 5.5 percentage points to end last year with 46.9 percent market share, versus 52.4 percent in 2008. Meanwhile Microsoft's Windows Mobile platform also lost out, shrinking by 3.1 percentage points to end 2009 in fourth place with 8.7 percent market share.

There's a clear pattern with each survey that comes out. Android and iPhone rise, while Microsoft's Windows Phone loses market share.
The Windows Phone drop was around 3% of the total handset market. But that equates to about 26% of Microsoft's share. That means Windows Phone loses 26% market share in one year.
Microsoft announced that it will have a new version of Windows Phone at the end of the year. However, I think it will be too late.
