Yet at the same time, the iPhone is %55 of Verizon's sales, and the iPhone is not the only iOS device, with the iPod touch doing pretty well (7M last quarter) and the iPad having essentially no competition and growing around %100 a year.
To me, this implies that a very large number of the android phones being activated each day are outside the USA, and I suspect to people who otherwise would have bought a feature phone. It looks like the difference in distribution (android's distribution is much broader since it has more hardware partners who have more longstanding agreements with more carriers) is the key to the difference in activation numbers.
