Hang on. 35% of Americans?
Only 35% of Americans with cell phones have a smart phone to begin with.
That just doesn't pass the smell test.
First off, ~85% of american Adults have a cell phone right now.
That would mean that more than 40% of those are planning on getting an iPhone 5?!
Right now 25% of smart phones in use are iPhones. That means right now less than 9% of Americans with a cell phone have some form of iPhone.
A huge number, but even if iPhone use among smartphone users doubled, AND smartphone use in general doubled, you still wouldn't get to 35% of Americans using an iPhone, and that assumes that EVERYONE with any previous iPhone would replace it with an iPhone 5.
I know a lot of people with iPhones, but a lot of those are still 3GS models, or even 3G models. One guy in my office still has his original iPhone that he bought on day 1. He is going to get an iPhone4 when the 5 comes out.
That 35% number is just not adding up.
