And reveals that more than half of EU5 smartphones are still made by Nokia.
More than half of the smartphones being used in the five largest European markets are Nokia handsets, according to comScore's latest research.
Its MobiLens survey for July 2010 shows that 51.2% of smartphone-owning respondents in the UK, France, Germany, Spain and Italy have Nokias.
However, comScore warns that Nokia's EU5 smartphone market share has fallen 14.4% since July 2009 - during which time, smartphone adoption in these countries has grown by 41% to 60.8 million people.
Symbian is still the most popular smartphone OS in the EU5 by usage, with 54.4% of respondents using Symbian phones.
However, that share has fallen 14.4% since July 2009 too, with both iOS and Android growing their shares in that period by 5.3% and 5.6% respectively.
There's a story to be told here, though. comScore supplied ME with a breakdown of the smartphone OS market shares in each of the EU5 countries, as well as the US.
Let's start with the US:
BlackBerry remains top dog with a 39.3% market share, but iOS and Android are taking decent chunks of the market too.
Now check the stats for the UK and France, which have broadly similar splits:
Symbian is the most popular smartphone OS in both countries, but it's facing strong competition from Apple's iOS, which has more than 30% of the market in France, and is nearing that figure in the UK.
Note Android's 16% share in the UK - but also the absence of Palm's webOS, which comScore says has too few users to register in its survey in these markets. Windows Mobile outguns both BlackBerry and Android though.
Now look at the OS breakdown in Germany:
Symbian still has half the smartphone OS market here, and although iOS has a 21.2% share, it's notable that Android and BlackBerry both have a way to go - in fact, WinMo is well ahead of their combined share.
And now see the charts for Italy and Spain:
Who said Symbian was dead in the water? It remains the dominant OS in these countries, although these charts represent usage rather than sales of new handsets.
It's clear that in Southern Europe, iOS and Android have a way to go, though, in gobbling up market share.
Are they immature markets in terms of their smartphone adoption? Actually, no. They're the two largest countries in terms of the percentage of mobile users with a smartphone - 34.1% for Italy and 31.9% for Spain.
Meanwhile, the UK, Germany and France have 28.5%, 20.3% and 19.3% smartphone penetration respectively - while the US has 22.8%.
