Yes! However, iOS 'hides' the scrollbars by default (its part of their Human Computer Interaction Guide) so my guess would be that your problem lies herein.
A quick search on Stack Overflow shows that there aren't a lot of quick fixes. You can try an external JS-lib (jqueryUI for instance or iScrol: http://cubiq.org/iscroll-5) but this requires knowledge of coding.
Another solution would be to use a simple visual cue to show that the user can scroll, for instance a small arrow or 'scroll for more' text.
I do think you need to code to fit a more complex solution. You want to override basic iOS behaviour which, in my experience, is a pain in the butt.
