In iOS5 this works fine:

[descriptionWebView.scrollView setScrollEnabled:NO];

But in any iOS under 5 it fails with:

[UIWebView scrollView]: unrecognized selector sent to instance 0x791f9e0
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIWebView scrollView]: unrecognized selector sent to instance 0x791f9e0'

    The issue isn’t the setScrollEnabled: call. It’s actually that the scrollView of the UIWebView wasn’t exposed until iOS 5 (which is why it fails on anything else). See the UIWebView documentation for further information.

    In previous versions of iOS, you had to resort to iterating through the subviews of your UIWebView to find a UIScrollView.
