How to get the scroll bar with CSS overflow on iOS
Developing an iPad website I tried to use the CSS property overflow: auto to get the scrollbars if needed in a div, but my device is refusing to show them even if the two fingers scroll is working.
I tried with
overflow: auto;
and
overflow: scroll;
and the result is the same.
I'm only testing on an iPad (on desktop browsers works perfectly).
Any ideas?

[Starting] with ios 5beta a new property
-webkit-overflow-scrolling: touchcan be added which should result in the expected behaviour.

Original answer, left for posterity.
Unfortunately neither overflow: auto, or scroll, produces scrollbars on the iOS devices, apparently due to the screen-width that would be taken up such useful mechanisms.
Instead, as you've found, users are required to perform the two-finger swipe in order to scroll the overflow-ed content. The only reference, since I'm unable to find the manual for the phone itself, I could find is here: tuaw.com: iPhone 101: Two-fingered scrolling.
The only work-around I can think of for this, is if you could possibly use some JavaScript, and maybe jQTouch, to create your own scroll-bars for overflow elements. Alternatively you could use @media queries to remove the overflow and show the content in full, as an iPhone user this gets my vote, if only for the sheer simplicity. For example:
<link rel="stylesheet" href="handheld.css" media="only screen and (max-device width:480px)" />
The preceding code comes from A List Apart, from the same article linked-to above (I'm not sure why they left of the type="text/css", but I assume there are reasons.
