In the latest research report from Nielsen, data from May suggests that Apple's iPhone iOS and Android OS are the only two mobile operating systems that are actually increasing in U.S. market share. Nielsen makes the point that smartphones are now the "majority of new cellphone purchases," and the iPhone is continuing to see increased adoption in the United States.
Following a May survey of U.S. mobile customers, it has been determined that Android and the iOS platform gained a percentage of smartphone market share, while other competitors like Blackberry actually fell in market share.
