Apple's iOS platform has managed to capture the lead marketshare in the US for a second month running, according to data from Kantar Worldpanel ComTech monitoring American smartphone sales for the past 12 weeks ending on the 23rd of December. As with the last report, iPhone sales accounted for the majority of overall sales at 51.2 percent, a drop from the previous 12-week total of 53.3 percent but a huge gain from the same quarter a year ago. Android share suffered only a small year-over-year drop.
