According to recent statistics from market research firm comScore, Apple boosted its share of the U.S. smartphone market to 39%. The three-month percentage growth is outperforming Samsung by a factor of four. comScore’s MobiLens service found Apple’s iPhone to have kept its spot at the top of America’s smartphone user market which now stands at 136.7% million people.

The Cupertino California company’s handset grew its share of the market by 2.7%, moving from 36.3% to 39% over the three month period ending in March. The jump was the largest seen of the top five OEMs, one that represented the only grown in brand market share aside from Samsung.

The South Korean electronics manufacturer posted market growth of 0.7%, moving from 21% to 21.7% Samsung’s share of the market is over two times that of number three HTC, which lost ground during the first quarter, falling from 10.2% share to 9%, a drop of 1.2 points. The fairly large hit to HTC’s U.S. market share allowed fourth and fifth place, Motorola and LG, to move closer to the faltering Taiwanese manufacturer. While still putting up losses, Motorola managed to keep an 8.5% share of the market, falling 0.6% LG’s piece of the pie went from 76.1% to 6.8% during the quarter.

As Apple’s line of iPhones only run the iOS platform, the mobile operating system also enjoyed a 2.7% bump and was the only OS to see growth in the March quarter. Google’s Android platform was still on over half of all U.S. smartphones but its share dipped 1.4% over the three month period, going from 53.4% to 52% Number three BlackBerry shed 1.2% to move from 6.4% to 5.2%, while Microsoft’s Windows phone platform put up slight growth of 0.1% to end the quarter with 3% of the market. Symbian was the platform that rounded out the top five, dropping its market share from 0.6% to 0.5%.

As of right now, American smartphone users now make up 58% of the entire mobile market, a figure up 9% since December. With carriers offering deep subsidies and aggressive pricing, the number will most likely continue to grow for the foreseeable future as Internet-connected handsets quickly take over so-called feature phones. We’ll just have to wait and see though.
