Sprint has posted the results of its holiday quarter, during which it suffered a net loss of $1.3 billion. The company blames that partly on subsidies for the Apple iPhone, however, of which it sold a record 2.2 million, compared to the 1.5 million it activated in each of the three previous quarters. 38 percent of Q4 iPhones were sold to new customers. In all Sprint sold over 4 million LTE smartphones throughout the quarter, including the iPhone.
