The iPhone 5s has been the top-selling smartphone at each of the four U.S. carriers since launching in September.
According to data compiled by Canaccord Genuity analyst T. Michael Walkley, the Apple device has been the highest-selling phone for AT&T, Sprint, T-Mobile and Verizon in September, October and November. The analyst report was cited by AllThingsD.
Prior to the release of the iPhone 5s, the iPhone 5 was the top phone at only one of the carriers, AT&T. The other three carriers were dominated by the Samsung Galaxy S 4.
With Apple climbing back on top thanks to the iPhone 5s, it now appears the Cupertino, Calif., company may have also found some success with the iPhone 5c.
Despite being heavily discounted from various retailers since the day of its launch -- usually a sign of poor sales -- the iPhone 5c has been among the top three selling smartphones at each carrier in September, October and November, according to the Canaccord report.
Apple should be able to maintain its strong sales at least until March and April, which is usually the time of the year when companies like HTC and Samsung refresh their device lineups.
