how to clear autofill in safari iphone

I've called iPhone and they say you can't delete the autofill from safari, but you can. I have done it by,going into settings, then safari, then hit-clear history, hit clear cookies, hit-clear cache. Then go to search engine- check yahoo then goole. Your done. If you also want to your web pages gone turn iPone off then back on. Hope this helps someone. Apple surport should read this. Dave

ps: the page that is on the screen will not get deleted. That's the only thing you can't delete.
