Need more proof that the iPhone is still a juggernaut in the U.S. some five years later? Telcos consultant Benedict Evans crunched the numbers based on AT&T (T) and Verizon Wireless’s (VZ) quarterly earnings for Q3 and came to three conclusions. The first is that 80% of all devices sold last quarter on both carriers were smartphones. The second piece of info is 48% of all post-paid retail handsets sold were iPhones. And lastly, 60% of all smartphones sold on both carriers combined in Q3 were iPhones. As Evans points out himself, the figures aren’t complete yet because Sprint (S) hasn’t posted its earnings for the quarter, but the figures still tell a chilling story that Apple’s (AAPL) iPhone brand is holding on to its crown in the U.S., even if a sea of Android smartphones are creeping up fast.
