- Introduce the `$route` service, which allows binding URLs to views for routing and deep-linking:
  - Add the `ngRoute` module as a dependency.
  - Configure routes for the application.
  - Use the `ngView` directive in 'index.html'.
- Create a phone list route (`/phones`):
  - Map `/phones` to the existing `phoneList` component.
- Create a phone detail route (`/phones/:phoneId`):
  - Map `/phones/:phoneId` to a new `phoneDetail` component.
  - Create a dummy `phoneDetail` component, which displays the selected phone ID.
  - Pass the `phoneId` parameter to the component's controller via `$routeParams`.
