Android - clear history when navigating between Activities

Question

I have 3 Activities that my user continuously is looping through. When user is back to the main screen I need to terminate previous history so user cannot hit back button and end up on screen #2, what would be a good way to do something like that? BTW - I'm using 1.6 (API level 4)

To reiterate - say I don't know or predict the path which leads me to the original view. But once I load it I want to clear history that led user to that view. In 2.0 it's possible with overwriting Activity#onBackPressed but I need something like that in 1.6
