Updated iPhone OS Stats
We received a couple requests recently for the distribution of the iPhone Operating System versions we see throughout our network. The data below represents the percentage of worldwide traffic we saw from the iPhone and iPod touch from December 14-21st.
It shows that iPod touch users lag iPhone users in upgrading their OS; 97% of our iPhone traffic comes from 3.0 or higher, compared to only 68% of iPod touch traffic.
For developers working on Android applications, platform version might become even more important than it is for iPhone given the wide variety of handsets and capabilities already available. Fortunately, the Android team has announced a device dashboard based on devices that visit the Android Market. Visit the Android developer blog for details or the actual dashbaord for the most recent data.
Note: This data is based on the number of Android devices that have accessed Android Market within a 14-day period ending on the data collection date noted below.
