54 per cent of iPhone and iPod touch users are in the US, according to mobile advertising firm AdMob, which has just released its June 2009 Mobile Metrics Report.
The company estimates that 13 million iPhones and 12 million iPod touches have been sold to date in the US. However, globally, it thinks the ratio of iPhones to touches is more like two to one.
Western Europe accounts for 26 per cent of all iPhone and iPod touch users, with France, Germany and the UK being the three biggest countries in terms of sales.
Meanwhile, 7 per cent of users are in Asia, although that could change quickly if Apple launches the iPhone in China later this year as it hopes.
