Marco Arment’s Theory on Verizon iPhone Sales

Marco Arment, on the sales figures for Instapaper in the App Store:

The results are fairly obvious: I see huge spikes whenever there’s a new iPhone, iPod Touch, or iPad released, whenever they become available in a major new country, or whenever there’s a major reason for people to buy a lot of them (like the holidays).

But he didn’t see a spike for the Verizon iPhone.
