Google's just released the latest numbers showing the distribution of the various versions of Android. Ice Cream Sandwich has made the list for the first time, with Android 4.0 totalling 0.6 percent of the devices activated. That's actually split into two versions of ICS -- Android 4.0 through 4.0.2, which comprises the Samsung Galaxy Nexus, and Android 4.0.3, which is currently rolling out to the Samsung Nexus S. (The Galaxy Nexus will be updated to 4.0.3 in good time.)
In other unexpected news, Honeycomb (Android 3.x) has hit a total 3.3 percent, Gingerbread (Android 2.3) is up a bit more, now totalling 55.5 percent, and Froyo (Android 2.2) is down to 30.4 percent. Eclair (Android 2.1) has dropped to 8.5 percent, while Donut (Android 1.6) hit 1.1 percent, and Cupcake (Android 1.5) is at 0.6 percent.
Again, that's the first showing for Ice Cream Sandwich. We'll want to watch how quickly that one grows, whether it's from new devices (which we really hope to see soon), or software updates (which we hope to see just as soon).
Numbers are for the two weeks ending Jan. 3
