John Resig blogged about a few extant frameworks in November: http://ejohn.org/blog/iphone-javascript-apps/ . PhoneGap ( http://phonegap.com/ ) seems like the most capable (though my rating of capability is "number of times I've seen it blogged about"). For those of us with little Objective C and lots of JavaScript experience, these frameworks offer an easy vector to begin developing (basic) iPhone apps.
There is a mapping software company that has a similar strategy, though I forget the name.. out of England, I think. Their library is Objective-C, but if you look at the source it is apparent that most of the implementation is actually inside a WebKit window.
