Verizon Wireless Chief Financial Officer, Fran Shammo, today participated in Citi's Global Entertainment, Media & Communications Conference, and as part of his presentation, revealed some iPhone sales numbers for Verizon.

Shammo announced that Verizon had pumped through 4.2 million iPhones during Q4 2011, which is the same quarter that Apple launched their iPhone 4S. Q4's sales dwarfed Q3's sale numbers of the iPhone by more than double, from 2.0 million to 4.2 million. Apple sold just over 17 million iPhones during Q3, so if Verizon sold 4.2 million iPhones during Q4, Apple could've sold nearly 35 million iPhones during Q4 across the world.

Apple today announced they will report their holiday quarter sales and earnings numbers on January 24, where we should know more about their sales numbers, but in detail. As a result of the strong iPhone 4S sales performance, Verizon is expecting a reduction in its profit margin as they absorb the upfront subsidies paid to Apple for the iPhone 4S.

As time goes on, Verizon claw back their money from customers service contracts.
