How should I structure this application?

Question

I am writing an iPhone application which requires the user to enter their mobile no and pin code and press an accept button before they continue into the application.

Previously I had (each view is in a different Xib)

AppDelegate - if {registered add load RootView (which is main view) into NavigationController} else {load RegistrationView subview}

But then when the RegistrationView loaded it would appear under the status bar, also I then dont know how to load the main app with a nav bar after registration, on load it works fine but from the reg page it loads without the nav bar

Then I tried

AppDelegate - if {registered add load RootView (which is reg view) in NavigationController} else {load RootView and then immediately push HomeView}

But then the UINavigationController doesnt appear to work on the main page

What would be the best way to implement this? Should I put both home pages in the same xib?

I have found a temporary solution

AppDelegate - if registered {add load RootView (which is main view) into NavigationController} else {add load RootView (which is main view) into NavigationController and load RegistrationView as subview}

RegistrationView - on registration hide reg subview

In my app I get users to enter their username and password in a modal view:

[navigationController presentModalViewController:login animated:YES];

I call this in the applicationDidFinishLaunching: method of the app delegate. This gets called the first time the program is launched. The same dialog is displayed on authentication failure.
