Google's Android mobile operating system was the most popular choice among smartphone buyers in June, but Apple's iOS helped Cupertino become the top smartphone manufacturer in the U.S. last month, according to Thursday data from Nielsen.
Android now has the largest share of the U.S. smartphone market with 39 percent, followed by Apple and iOS with 28 percent. Research in Motion's BlackBerry, meanwhile, is down to 20 percent.
"Because Apple is the only company manufacturing smartphones with the iOS operating system, it is clearly the top smartphone manufacturer in the United States," Nielsen wrote in a blog post.
HTC, Motorola, and Samsung also had a pretty successful month. HTC's Android phones represented 14 percent of the smartphone market, while its Windows Mobile/Phone 7 devices nabbed 6 percent. Android-based Motorola smartphones, meanwhile, made up 11 percent of U.S. smartphones last month, while 8 percent of smartphone owners had a Samsung Android device. Samsung also sold about 2 percent of Windows Mobile and Windows Phone devices (click chart at right for more).
Earlier this month, comScore said that Samsung was the top U.S. handset manufacturer between March and May with 24.8 percent of the market, while Android nabbed 38.1 percent of smartphone OS market share.
Controversial June numbers from IDC, meanwhile, said that Android and Windows Phone would be the top two mobile operating systems by 2015. That might not be too far-fetched for Android at this point, but Windows Phone has thus far had a slow start. That could change, however, when Nokia starts releasing Windows Phone-based devices later this year.
