How do I unlock the next level in Angry Birds?
I'm currently playing Version 1.4.4 of Angry birds on. I have managed to get three stars in all sections in Poached Eggs, Mighty Hoax, Danger Above and The Big Setup. I have 17 golden eggs and stars in all of them. Now, nothing is happening.
How can I progress to the next bit?
I don't think any more levels have been released yet. As the game is updated, more levels will become available, so it looks like you're going to have to wait.
Edit: There have been some new levels released - The "Ham 'em High" level pack will become available once you update your application.
