In the second quarter, Verizon activated 2.3 million iPhones, far fewer than the 3.6 million that AT&T activated during the same period. To be fair, AT&T is selling two models right now: The current iPhone 4 as well as the 3GS, which is now .

A Somewhat Unfair Comparison

I've heard quite a bit of anecdotal evidence that despite its age, the 3GS continues to sell quite well--probably because of its price. It's somewhat unfortunate that we don't have a breakdown here by model: it give us a clearer picture of just how Verizon is doing.

For this fact, I'd caution anyone from jumping to conclusions just yet on the performance of Apple's iconic smartphone on Verizon. We should expect AT&T to outperform its competition just because of its sales advantage. Depending on how Apple decides to handle the release of the , that may continue.

There have been quite a bit of rumors floating around that the 3GS as a prepay device in developing markets as Apple looks to continue to expand its reach. If the 3GS indeed does escape the axe, I couldn't see why AT&T couldn't potentially offer three iPhone models.
