IDC confirms it: smartphones are now out-shipping feature phones in western Europe. According to the company's statistics, only 20.4 million feature handsets were shipped to the Old World during the second quarter of this year, representing a 29 percent decrease from Q2 2010. Quarterly shipments of smartphones, on the other hand, increased by 49 percent to 21.8 million units, marking the first time that they've surpassed basic phone orders. Smartphones also comprised 52 percent of all mobile shipments, which shrunk by three percent, collectively -- something IDC's Francisco Jeronimo attributes, in part, to Europe's brutal economic climate and Nokia's steep decline (see chart). On the OS front, Android once again came out on top within the region, thanks to a whopping 352 percent year-to-year increase in shipments, while Samsung controlled the manufacturing side, with 33 percent of the European market.
