I just did a quick one, it works fine. Make a copy of the Scroller 
Example in the Mobile Resources folder. Edit the main "imageScroller" 
group, add a locked field and delete all the images. Put some text into 
the field and set the height of the field tall enough to hold all the 
text. Mine was 800 pixels high. Set the width to something close to the 
width of the scroller control; mine was 300. Set the top of the field to 
the top of the scroller; mine was at 4.

Edit the card script. In the "contentRect" part of the preOpenCard 
handler, change the dimensions to that of your field:

   iphoneControlSet sScrollerId, "contentRect", (0, 0, 300, 800)

That's all I had to do. It scrolls smoothly up and down in the 
simulator. You can set the "canBounce" to true if you want it to have 
that little bob at the ends that iOS does.
