There's somehow a recurrent trend of people building frameworks and libraries to try and make HTML5 apps look like native ones. I am somehow dubious as to wether it is indeed a problem that should be solved: jQuery mobile for example is a nightmare when it comes to customizing the styling to your own taste and has a whole range of embedded mechanisms (routing anyone?) which create a swarm of conflicts when trying to use any modern JS MV* framework out there. A half decent designer will have no issue styling in a day the bulk of you app using simply CSS (and it can look gorgeous, especially on the iPhone), as long as you don't cripple your boilerplate with unnecessary iOS-ish effects and provide him with clean markup.
