How to change screen's in windows phone 7?

问题:

I am developing an app in which the user register to EULA then only he proceeds and is navigated to next page, but still after registration the app starts with EULA not the navigated page.

I recommend reviewing Peter Torr's advice with respect to navigation redirections and places.

This recent release may also be worth consideration.

If I'm following right, I'd do something like this:

Store a variable isEulaAccepted and then, in the Initializer method:

public EulaPage(){
  if(isEulaAccepted){
        NavigationService.Navigate(new Uri("/FirstPage.xaml", UriKind.Relative));
    }
}

This might not be the best solution, but I hope it helps.
