ComScore: Android And iOS Near 70 Percent Of US Smartphone Market Share

ComScore has issued a new report on the US smartphone market breakdown for the three-month period from April to July 2011. Unsurprisingly, Android and iOS continue their steady climb now reaching a combined market share of nearly 70 percent, while RIM, Microsoft, and Nokia's Symbian continue to slide.

Over the three month period, Android remained the fastest growing platform with a 5.4 percentage point change, now hitting 41.8 percent of US smartphone market share. It's dominance, however, hasn't stopped Apple, as iPhone shares also continued to grow, though at a more modest 1 point increase, now reaching 27 percent market share.

The biggest drop was seen by RIM, with a negative 4.0 point change down to 21.7 percent, while Microsoft's Windows Phone platform dropped off by 1 point to 5.7 percent and Nokia's Symbian is now at only 1.9 percent.

It will be interesting to see how things change with the various product launches set for this fall. Microsoft will be unleashing its Windows Phone 7 Mango handsets with the first batch expected to launch in September followed by Nokia's "Sea Ray" in October. But this may not be enough to counter the two market leaders that also have major announcements in the coming months.

Apple is expected to launch the iPhone 5 and possibly a lower-end iPhone 4S this fall. Android will have a new flagship phone running Ice Cream Sandwich among a myriad of other new Android phone releases.
