Sprint is the latest wireless service provider to report an earnings hit from subsidizing the iPhone.
The company had hoped to give the likes of AT&T and Verizon a run for the iPhone money when it cut a $15.5-billion deal with Apple to carry the white-hot handset. From October to December, Sprint activated about 1.8 million iPhones , compared with 7.6 million at AT&T and 4.3 million at Verizon Wireless.
