I've tried Blitting with my own scroll equations, and the performance is still sub-par to native iOS scrolling. Without Blitting it's a disaster.
Native apps can easily scroll 2000px of text with a swipe of the finger, but my AS3 apps run at MAYBE 20FPS.
I believe Flex has a new component for lists, but what about us Flash IDE developers?
I'm about to just build everything that needs to be scroll-able in Phonegap, even though their company sucks, their software breaks, and HTML5 is way behind Flash with animation.
i have a sloution for scrolling but i have a problem where i cant stop it from getting drag over the screen take a look at the post in that link it may help you
I have had very good results scrolling large sections of text and images using the Greensock Blitmask and DragProps and this was using Air 3.2. Perhaps Air 3.6 is even better.
