Apple does not break down sales figures for individual iPhone models. This hasn’t stopped Ming-Chi Kuo of KGI Securities from estimating first weekend sales numbers for the iPhone 5s and iPhone 5c.

As first noted by AppleInsider, the analyst estimates that of the 9 million iPhones Apple sold last weekend, between 3.5 million and 4.5 million were for the iPhone 5s. The rest, between 4.5 million and 5.5 million, were for the iPhone 5c.

Earlier this week, Localytics offered much different numbers. They said that the iPhone 5s was 3.4 times more popular than the iPhone 5c during the first three days of release. They based this on iPhones tracked through apps and customers. By contrast, Kuo’s numbers are “rooted in production.”

In noting the differences, Kuo states::

From Apple’s viewpoint, production, sell-in, sell-through and activation are different things. Since iPhone 5s is in shortage now, numbers of production, sell-in, sell-through and activation should be very close.

The gold colored iPhone 5s remains the one most sought after. The most popular iPhone 5c appears to be the pink model, according to one recent survey.

Apple’s fiscal year ends this weekend, so we’ll know soon enough just how many iPhones were sold during the September quarter.
