iPhone sales, though, don't show many signs of slowing. Apple sold a record 16.2 million iPhones during its recent fiscal first quarter, an increase of 86% compared to the same period last year. Since then, the tech giant started selling an iPhone on Verizon's network, marking the end of AT&T's (T) exclusive U.S. iPhone deal.
Verizon says that it will not release its iPhone sales figures until its first-quarter results later this month, although the telecom giant said that it sold more of the phones during the launch than any other product in the company's history.
With the iPhone providing a sizable chunk of Apple's revenue growth, investors hope the company answers questions on its iPhone 5 strategy when it discusses its second-quarter results after market close on April 20.--Written by James Rogers in New York. >To follow the writer on Twitter, go to http://twitter.com/jamesjrogers. >To submit a news tip, send an email to: firstname.lastname@example.org.
