I tried to make a simple calendar with swipe gestures with PhoneGap and Sencha. The performance was horrible on my iPhone 5 (!). Wouldn't use HTML5 again, except maybe as a wrapper for some static HTML5 content without much user interaction (exactly the kind of app that Apple doesn't like btw) However, here's an idea: I recently bought the Impact.js game engine. It comes with Ejecta, which is a hardware-accelerated "browser" for iOS that supports only the canvas-element. If you can manage to implement your HTML5-app in canvas only, this might be an alternative for apps that feel almost native. However, it might be too troublesome to go down that path.
