I would like to point the index page of my app to an existing mobile friendly site
the site will get real time updates and i would like the app to render the latest content
the interesting part is that the site has a lot of images that will not change for years
it would be great to pre-load the static images for a really fast app user experiance
Keep as much of your app local to the device as possible. Fetch changes to the content via XHR/AJAX or FileTransfer.
If you need to manage code updates (or any update, really), you might also investigate hot code push, like this: CodePush
