Google has updated the developer dashboard with new platform distribution numbers, and they show a nice uptick for Google's latest and greatest. Jelly Bean (versions 4.1 and 4.2) have reached 33% of active Android devices, or roughly one-third of the market. Gingerbread, however, continues its slow slide downward while remaining stubbornly high.
Last month Gingerbread was chugging along at 38.5%, so the last 30-days saw a 2% drop. That's actually a slight acceleration in the rate of decline.
