Google Analytics logs are beginning to emerge revealing a couple of different versions of Android. It makes for fascinating reading. In the screenshot above you can clearly see Android 2.3 which we now believe to be Gingerbread. Looking further down the list you can also see 3.01 which is thought to be the version of Android after Gingerbread. We know little about 3.01 except that it is rumored to be called Honeycomb.
The logs indicate the operating system of devices accessing certain sites. We could be witnessing future versions of Android being tested on unknown devices. Equally this could be from users that have modified their devices to portray a different version of Android.
