Another quarter has come and gone, and you know what that means: Nielsen ratings are out again. The latest batch of numbers don't reveal anything wildly new, but they're still just as telling nonetheless: 44 percent of mobile subscribers in the US use a smartphone in the US. Of those, 71 percent are in possession of an Android device or an iPhone. Additionally, 56 percent of all phone purchases during the third quarter were smartphones. And -- this probably won't come as a surprise to anyone -- at a decisive 42 percent, Android remains the number one smartphone OS while Apple is still perched firmly on top as the leading manufacturer (28 percent).
