Every month Google releases a handy chart telling us what version of the operating system folks are using out there. This month, they did things a little differently and now collect data only from devices that have visited the Google Play store in the past month, versus all phones that checked into Google's servers as done in he past.

It didn't make much of a difference. Jelly Bean continues to climb and is now at 25-percent, Gingerbread is down 5-percent, and lower version are clinging to life support. The one change we didn't expect is Ice Cream Sandwich to actually climb while devices were getting update to Jelly Bean. We'll write that off to the new collection method.

If you're a developer, this will help you decide which devices to target. If you're just an interested fan, the data sure is fun to talk about.
