In the US, the iPhone 4 took the top spot, followed by the iPhone 3GS, and the iPhone 4S. The BlackBerry Curve 8530 and the HTC Evo 4G occupied spots 4 and 5.
Taking a look at the EU5 chart, the iPhone 4 came in first, followed by the iPhone 3GS. The Samsung Galaxy Ace S5830 and Samsung Galaxy S II came in 3rd and 4th. Finally the iPhone 4S took up the rear in 5th.
It is definitely interesting to see how strong the iPhone 3GS continues to perform even though there are 2 successors available. We assume that much of its success can be attributed to the low price point.
Overall, both US and European markets saw a growth in the sales of smartphones. In the seconds half of 2011, the US smartphone market grew 14.8% to encompass 41.8% of all mobile users. The EU5 saw a 13% growth to 44% in the same time period.
