Well I guess the best thing we can do is to keep making a stink about it on the board so that Apple engineers continue to be aware of it.
At this point the best thing we can hope for is probably that when the iPhone OS gets upgraded to Leopard it will change enough of the underlying system to pretty much eliminate the problem. Now it's just a matter of when we get the big Leopard update.
Yes, I have had quite a few crashes of Safari, just a sudden quit of the app. This has happened even after a power-off/on cycle. I surely hope they can get this fixed.
Obviously this still happens sometimes for some people but my experience is that it's become much less common. Under earlier revisions the iPod would crash for sure if you used Safari for more than a few minutes. Now it seems like certain pages or sites still cause problems but it doesn't happen all the time.
