8.7m Android phones versus 10.7m iPhones in the US reckons AdMob
Indeed, the numbers from AdMob's Mobile Metrics report for April which analyses the data from the firm's 23,000 mobile website strong network claim Android is running iPhone pretty close in the US, yet trails by some distance in Europe and other major territories.
Born in the USA
According to devices that have connected to AdMob's network, there are 8.7 million Android handsets in the US compared to 10.7 million iPhones.
But when iPod touch and iPad sales are taken into account bouncing iPhone OS's total to 18.3 million the ratio between the two is 2:1.
Worldwide that ratio stretches to 3.5:1, with 11.6 million Android handsets versus 27.4 million iPhones and 40.8 million iDevices in total.
Such figures suggest Google has sold less than 3 million handsets in territories outside of the US, with North America accounting for 75 percent of Android's userbase.
Significantly, there were more Android devices than iPhones in China in April 2010 in the AdMob network however. The top three Android devices in China were the HTC Hero, HTC Magic, and HTC Dream.
All aboard iPhone
AdMob's stats suggest iPhone enjoys a much wider global spread, with North American sales making up 49 percent of total sales.
This makes sense considering that iPhone has been available for much longer than Android devices, as well as being better supported by operators.
"Although Android has a notable presence in the US, the iPhone platform has a much larger global reach," AdMob summarises in the report.
"Over the past 12 months, the iPhone platform has grown faster internationally than in North America. The iPhone OS experienced its strongest growth in the past year in Asia (474 percent), Oceania (367 percent) and Western Europe (269 percent)."
The top five countries with the most unique iPhone OS devices were the United States (44 percent), United Kingdom (9 percent), France (6 percent), Canada (5 percent), and Japan (4 percent).
The top five countries with the most unique Android OS devices were the United States (75 percent), China (8 percent), United Kingdom (3 percent), France (2 percent), and Germany (2 percent).
