First of all, we've found out that more than 200 million iOS devices have been sold until now.
According to Apple, 25 million of those are iPads - so the company sold 10 million iPads since March this year, when the number of units sold was reported to be 15 million.
Apple didn't say how many iPhones it sold to date. However, we know that there were 100 million units sold in March. We also know that the company shipped more than 60 million iPod Touches as of the same month. Certainly, there have been several more million iPod Touches sold since then - let's say 5 million at most. This would mean iPhone sales hit 110 million (probably more, though) by now. So, about 10 million iPhones were sold since March.
The conclusion: customers bought 10 million iPads and (at least) 10 million iPhones in the last three months. That is something.
Also interesting: it took Apple three years to sell the first 100 million iOS devices (since June 2007, when the OS was called iPhone OS), and only one year now to ship another 100 million (from June 2010 to June 2011). 100 iOS million devices in one year – that's comparable to the total number of Android devices shipped since Google's OS was first launched (September 2008).
