Verizon posted results on Thursday for its winter quarter that rode heavily on iPhone sales. It added a total of 1.8 million new customers, 906,000 of which were regular cellphone subscribers, but was propped up chiefly by 2.2 million iPhones being activated in the network. The carrier also disproved speculation that the HTC Thunderbolt was outselling the iPhone and noted that just 260,000 Thunderbolts had been activated in the two weeks the 4G phone was available.
