Verizon reported winter quarter results that were defined by smartphones, albeit with current gaps in its data. The company saw a slight 4.6 percent increase in revenue to $28.2 billion but a much wider 15.7 percent jump in its net profit, which it quantified as 59 cents per share. Smartphones were key to the growth, Verizon said: 6.3 million were sold in the period, making up 72 percent of all its subscription phones.
