It was fixed in Safari 3.2 for iPhone and iPod in July and for PC in November.

Repro here.

I have also created proof of concept code that shows potential exploitability and demonstrates how to use heap-spraying in Safari. AFAIK this is the first use of heap spraying in Safari, but I may be wrong. Heap spraying in Safari is not that different from other browsers, just backwards ;) The code can be found here.
