Help: Smartphone OS marketshare for 2009 Europe vs USA

A question in from one of the MIR readers this afternoon:

Hi ewan
a quick question for you.

im trying to find a breakdown of smartphone OS market share for 2009 for europe vs US. basically comparing, symbian with apple, rim, windows mobile and android. i cant seem to find a european or us breakdown. i can find lots of global numbers but i know that US and europe are different (mainly the fact that nokia has no presence in the US). i just need something pretty simple.

do you have something you can send to me?

thanks

I wrote back saying that I don’t have any precise statistics — do you have any to hand? Or any suggestions where I can point the reader?
