Following IDC’s report this morning that highlighted Apple’s continued growth among mobile phone marketshare worldwide, while coming second to Samsung in global smartphone marketshare, research firm comScore just released its numbers for United States mobile subscribers for the three-month period ending March 2012.

According to comScore, Apple posted impressive growth during the quarter with 30.7-percent marketshare among smartphone platforms in the U.S (up from 29.6-percent). Increasing from 47.3-percent in December 2011 to 51 percent in March 2012, Android was able to grab the top position for platforms during the quarter. Growth for Android and iOS continues to come at the expense of RIM. The company grabbed just 12.3-percent of the platform market in March, which is down from 16 percent in December 2011. Microsoft also lost marketshare with 3.9-percent, which is down from 4.7-percent…

Mirroring IDC’s report, comScore’s numbers show Samsung as the top OEM in the U.S. with 26 percent of mobile subscribers (up from 25.3 percent in December 2011) versus LG’s 19.3-percent (down from 20 percent) and Apple’s 14 percent (up from 12.4-percent).

As we noted in the report of IDC’s numbers earlier, exact numbers on the amount of devices shipped/sold by Samsung and many other Android vendors are not made publicly available. However, we know Apple shipped sold 35.1 million iPhones during the quarter, which is an 88 percent YOY increase.

ComScore’s research comes from surveys of over 30,000 mobile subscribers in the U.S. during the three-month period ending in March.
