Good question, what are the Android/iPhone market numbers outside the U.S.? I suspect that Android might have a lead in undeveloped countries since there are lower cost models available. I'd love to see the data.
According to some numbers I can find for Sweden (which probably doesn't classify as an undeveloped country), Android caught up with iPhone during Q1 of this year (1), and is currently growing faster than iPhone.
