Help with iPhone

I need some help with iPhone. I use iui but I don't understand the basics. It seems that I can't do a simple update of a post using Ajax. Is that done for you?

What if I want to delete a post in the db, from a "show" view. How do I write the delete link and the method? How do I get back to the view I want after that.

Got it working using a normal link_to and target _replace. But I the "backButton" has the wrong innerHTML and href. How can I change that? Can I add some variables to the link_to?
