After close to one week of sales, we found that, overall, New York, Los Angeles and San Francisco held the largest market share in the U.S. for iPhone 5s and 5c activations. This is to be expected given the size of their populations. However the real surprise was that San Francisco came in third. Considering San Francisco is actually the 11th largest market in the U.S., its status as a technology haven also, clearly, translates to a culture of early adoption.
We then looked at the distribution of the iPhone 5s and 5c for each of the cities. Again, San Francisco stood out, showing the strongest preference for the 5s over the 5c (85% vs. 15%) among the top 12 major U.S. cities. Philadelphia showed the lowest preference with 72%.
Notably, iPhone 5s and iPhone 5c devices represented 1.4% of all active iPhones in the U.S. on September 22nd. By September 26th, this had risen to 2.0%. While the iPhone 5s maintains its lead over the iPhone 5c the gap is narrowing slightly. On September 22nd, the iPhone 5s was outpacing the iPhone 5c by 3.4x. That decreased to 2.9x by September 26th.
AT&T saw the highest adoption rates with the new devices accounting for 1.02% of the iPhones on its network by September 26th. Verizon was next with .70%, Sprint reached 0.18%, and T-Mobile was in last with 0.12%.
