Do Anroid phones have greater market share than iOS phones?
Yes, all of the current Android phone models from all of the companies producing Android phones on all cell carriers now have a total combined US market share that is greater than the one iPhone sold by Apple on one carrier.
I'd love to see the 1Q11 numbers that will include a month and a half of Verizon iPhone sales. The pent-up demand is supposed to be incredible, and they've stockpiled massive numbers of CDMA iPhones for the launch. Even my wife, no lover of things Apple and current Android user, is thinking of getting an iPhone in a couple months when her window hits.
This is off topic for this thread, but I'll answer.
At the moment, I think they're close to even. We'll see what the future brings with Verizon and other coming developments. The bigger picture, though, is that iOS devices have far larger market share. That would be the sum of iPod, iPhone and iPad sales, versus nonexistent Android music players and miniscule Android tablet sales.
So, for developers iOS remains by far the most attractive target, since not only are there far more potential customers, but the vendor has a reasonable expectation of getting paid for his product.
