I am trying to scroll an iframe on iOS, and I succeeded, it\'s scrolling well, reference:
http://home.jejaju.com/play/iframe-scroll.html

I found a combination of div with "absolute" style and nicescroll do fix choppines.
You have to load nicescroll on the page loaded by iframe. In the same page wrap all you content with a div (with style absolute)
#content { position:absolute; }
Load nicescroll using wrapped div content.
$(document).ready(function() {
$("html").niceScroll("#content");
});
Link to demo page, so you can check the code: http://areaaperta.com/nicescroll/demo/iframe6.html
Automatically, with iOS native scroll has used, in other platform you got nicescroll active.
I have test on iPad with iOS 5.1.
