Basically all you have to do to get Android 1.5 and 1.6 compatibility is to use
translate(x,y) instead of
translate3d(x,y,z). In fact iScroll v3.3 checks if your phone supports 3d functionality and use the best option it finds.
The problem here is that
translate(x,y) seems not to activate the hardware acceleration, so do not expect blazing fast scrolling. To reduce lagginess to the minimum, iScroll disables all the eye candies and wisely preserves resources. Momentum, bouncing, and scrollbar fade in/out are all disabled but at least you can scroll.
We are now back in beta. I need the help of all the (un)lucky owners of an Android 1.5/1.6 and receive some feedback. My question is: should we really target version < 1.6? If scrolling performs so badly shouldn't we just pass over? If you don't care about Android, fear not: version 3.3 adds some new features and improves overall stability for you too. So go get the new version.
