if one builds an "app" , since it uses a "webview" inside a native application , it is always "native" ( except for firefox and likes os where the browser is the "os" ). Phonegap and likes use native code so one can bundle html+js into a native app.
I tell my clients , instead of using a wrapper , to build a webapp directly. most of the LOB-apps require an internet connection anyway , and things like camera can be accessed from the browser now , on most mobile os. And it is easy to explain clients how to bookmark a webapp to the home screen.
packaged webapps are overrated imho , in most cases a webapp makes more sense.
