Basically I followed instruction on the pdf from Adobe for optimization.
I have changed the images so that are 2^n pixels.
I have added cacheAsBitmap= true on most of the sprites
I have also changed the Tweener classes with the standard Adobe Tween ones, just to have a smoother motion.. Not sure if this helped, but because I didn't really need anything special, I preferred to have the standard one.
I've tested this on ipod touch, iphone 3g, iphone 3, and ipad.
I also changed the Mochi leaderboard with a custom class using SharedObject to store locally the top ten.
And another thing I did. I removed all the frames from the main timeline and changed all the screens with sprites (with cacheAsBitmap=true) for the help pages, etc.. Not sure again if this is worth, but I preferred to have 1 single frame in the timeline and left all the rest via AS3.
