iPhone leads competition in UK holiday smartphone sales

Citing findings by research firm GfK, the Financial Times reported on Monday that Apple’s iPhone 4S accounted for nearly one out of every four smartphone sales in the UK during the lead up to the holiday season and retains the best-selling smartphone in the UK.

During the first week of December, five versions of Apple's handset, including the two and a half year old 3GS, ranked as one of the top 15 smartphones sold and took over 37 percent of a smartphone market that nearly doubled in size between Feb. 2010 and Aug. 2011. According to figures from Ofcom, the U.K.'s government-approved regulatory authority for telecommunications, 46 percent of all mobile users are now smartphone owners.

Apple’s rivals are also showing significant grown in sales. The second best-selling smartphone in the UK is Samsung's Galaxy S II and three versions of RIM's BlackBerry Curve all landing in the top ten. Noticeably absent from the top-selling handsets was Nokia. The company's new partnership with Microsoft has yet to bear fruit. The Windows Phone 7-based Lumia line failed to crack the top ten handsets sold in the UK after.
