"Jiggy" is a native iPhone app that hosts these little Jiggy apps, which are written in JavaScript but have nothing to do with HTML/CSS. The site talks about "Jigglins" which are written in Objective-C and add functionality to Jiggy, like the one they wrote that exposes part of UIKit (the iPhone's GUI API).
So you need these little Jigglins wrappers for every Cocoa API you want to use. They do mention a code generator that I assume is for this purpose though. I assume that's how PyObjC and RubyCocoa do it to.
All in all, this is an interesting idea, and it might be nice for simple apps and experimenting. But I've written some iPhone apps, and I can tell you this just doesn't seem worth the trouble. I did try installing it, and it seg faulted, so I gave up. We'll see once it matures a bit, but by then Apple's iPhone SDK will most likely be out (hopefully with Objective-C 2.0's garbage collection).
Plus, the fact that javascript is garbage collected doesn't mean that jiggy is. If they are really just calling out to objective-c libraries, than either they are doing their own really tricky memory management, or they'll have to force it up to javascript.
