Esqueci msm.
Em relação ao tema, vi isso aqui http://developer.android.com/design/patterns/navigation.html:
Navigating to screens with multiple entry points
Sometimes a screen doesn't have a strict position within the app's hierarchy, and can be reached from multiple entry points—such as a settings screen that can be reached from any other screen in your app. In this case, the Up button should choose to return to the referring screen, behaving identically to Back.
Parece que implementei certo então.
Quando vi, já tinha enviado.

Então o código ficou assim:Então fiquei me perguntando qual seria a utilidade do NavUtils neste caso?Serve somente para quando se quer atribuir um comportamento diferente ao botão up ?Pelo que entendi também, o NavUtils não sabe qual a Activity anterior exceto se previamente registrado no AndroidManifest.xml.
