Prior to the September launch of the iPhone 5s and 5c, Apple’s sole entrant among the top three at the Big Four carriers was the iPhone 5. In addition, it held the top spot at only one carrier, longest-time partner AT&T. It fell to second place at Verizon Wireless, Sprint and T-Mobile, where Samsung’s Galaxy S4 held sway.
Since September, though, things have changed. As of November, in fact, the iPhone 5s held the top spot at all of the major carriers, while the iPhone 5c held the number three rank at them, as well. Meanwhile, the Galaxy S4 held the second position at Verizon Wireless, AT&T, Sprint, and T-Mobile.
In past months, since the Sept. launch of the 5s and 5c, the 5c even held the second position in many instances.
Based on these numbers, Walkley has raised his first-quarter 2014 iPhone shipment estimate from 52 million units to 54 million units.
