I have been struggling with fixed positioning in iPad for a while. I know iScroll and it does not always seem to work (even in their demo). I also know that Sencha has a fix
using jquery i am able to come up with this. it doesnt scroll smooth, but it does the trick. you can scroll down, and the fixed div pops up on top.
THE CSS
THE HTML
fooo
THE jQUERY
Finally we want to determine if the ipod touch in landscape or portrait mode to display accordingly
