Not sure why it matters to you or why it is funny? I have been running 4.2.2 for a while now, because I have a developer community and the option to root.
Additionally, they lump every Android phone into this pie chart statistic, when what should be viewed (for comparison to Apple) are flagship phones. How many S3's, HTC Ones, Note 2's, etc are running Gingerbread, ICS and Jelly Bean? Look at those stats if you actually want to compare to Apple. You will see a very similar pie chart as Apples when only the high end Android and Google phones are broken down. Instead every single one of those billion handsets running Android are added.
Or Maybe we should include every iPhone, iPad, iPod ever made into the Apple pie chart? All of a sudden, things wont look so pretty. All those 3G's and 3GS's and ipad2's/ipods would make your pie chart look a lot more like Androids. But only the iphone 4 and above are included. I mean, iOS 6 has been out for over 6 months and all those iphones aren't on it? Sad, right?
