According to Nielsen's May survey, smartphones accounted for 55% of U.S. cell phone purchases in the prior 3 months, up from 34% a year before. Google's (GOOG) Android maintained a 27% share of purchases, while Apple's (AAPL) iPhone grew from 10% to 17%. This could add to fears about the iPhone slowing down Android's U.S. growth.
