Samsung lawsuit forced disclosure of iPodTouch sales http://www.appleinsider.com/articles/11/04/19/apples_samsung...

Even first day iPad sales blow through http://allthingsd.com/20100405/apple-300000-ipads-sold-on-fi...

etc.

StatCounter has mobile browser usage (which includes all iOS devices)[1]:

Symbian: ~33% (it's big in Asia, and still has a large installed base)

iOS: ~20%

Android: ~18%

BB: ~12%

Note that this is only browser usage, which obviously doesn't correspond to total sales well. Symbian is still way ahead of anything else in that measure.

The only market share numbers I've seen recently that included non-phone devices were straight from Apple (so feel free to take it with a grain of salt if you'd like). They have iOS at 44%, with Android at 28%.

Granted, it's a figure from Apple, but at WWDC, they touted iOS as having 44% mobile OS market compared to Android's 28%.
