During Apple's second quarter earnings call, CEO Tim Cook has blamed the company’s failure to meet Wall Street’s expectations for iPhone 7 sales on rumors about the next iPhone, "We're seeing what we believe to be a pause in purchases of iPhone, which we believe is due to the earlier and much more frequent reports about future iPhones," Cook said during the company's second-quarter earnings call with analysts on Tuesday. "That part is clearly going on... We are seeing that in full transparency."<br /><br /> During the recent March quarter, Apple sold 50.7 million iPhones, representing a rather modest drop from the 51.9 million units Apple sold in the same quarter a year ago. The new models, which will mark the iPhone’s 10th anniversary, are slated for release in September or October.
