What happens here is that application view is redirected to that site and it is no more hybrid application... and this have some limitations not only the downloads:
Second Apple will not approve such application if you intend to publish it on App Store.
Third the application performance over slow mobile network will be much better if you make a hybrid application and only consume data. This can be done using Kendo Mobile for example with pages, scripts, image and all resources in Icenium and call the server for data, authentication or other back-end methods using ajax requests.
