How to change the startup page of a WP7 Application

I am having an WP7 application in which I need to change the Startup page depending upon if the user is already registered or not. Suppose if user is registered then I need to redirect him to welcome page if not then to register page.

I have tried a couple of ways below is my code but it gives me an argument dispose exception.

To achieve above feature I wrote Navigation code in my MainPage.xaml constructor. Checked if the User Registration info is not in isolated storage then will redirect to other page.

    private void IsAgreeed()
    {
        try
        {
            isoStorage = IsolatedStorageFile.GetUserStoreForApplication();
            if (!isoStorage.FileExists("DataBase/MyPhoneNumber.txt"))
            {
                this.NavigationService.Navigate(new Uri("/EULA.xaml", UriKind.Relative));                   
            }
            else
            {
                return;
            }
        }
        catch (Exception ex)
        {
            Debug.WriteLine(ex.ToString());

        }
    }

Above code works properly when I use it first time but if I Close the Application and restart it again it throws exception argument dispose exception.

Thanks; nil

To achieve this I put up MainPageorEula.xaml and got the functionality required.

Peter Torr covers page redirections quite well here. Two methods are offered with relative merits covered. Edit: Note you can redirect to a login page, rather then employing the popup suggestion for login handling.

I'd also recommend familiarising with his accompanying post on places here.

This address back stack handling (certification consideration) and addresses scenarios such as login pages.
