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?
