Design for iPhone and iPad, when iPad shows all Container Views and iPhone, just some of them

So, using Xcode 6.1.1, I have sizing classes included in the Storyboard.

My plan is in iPad dimensions, I will have a visible number of 4 View Controllers. Each of them has interrelated data that changes when the login is throttled in another view controller using NSNotifications. Since it has multiple view controllers, I added container views to the storyboard.

When the app is loaded on the iPhone, I want to use two view controllers instead

• to enter input (number 4 in the image)

• and a wizard (number 3 in the image) with the ability to display detailed views (numbers 1 and 2 in the image) as modal views

My question is that I understand how to set up the iPad so that all view controllers interact with each other, but in the iPhone they see how to enable navigation so that the user can access the details?
