I have managed to get flash on my android working for firefox with a bit of a hassle.
And then puffin as well, inbuild flash support, no hassle, costs 2 euro's or so.
That said, annoying decision. This whole html5 stuff is all nice and progressive.... but it's a damned pain in the ass for me.
I now have to ensure my own web software works in html5 no flash.....but, due to soooo many compagnies still running winxp with ie7...it also has to keep working in flash, gah!
