Requesting a tutorial using UITabBarController and UINavigationController

[amb1s1]

I see a lots of tutorial online, but I have not seeing one using a Uitabbarcontroller and Navigation controller like the Ipod. I would like something like this:

a tabbarcontroller with one of the tab with a Navcontroller and the other with a regular view. I saw one tutorial that did this, but everything was done in one NIB, I would like one that use diferent NIB for each Tab Item. Thanks
