With the new iOS firmware 4.2 out, I'm hoping someone will be able to answer my question: Will games need to be re-played in order to gain achievements? For instance, I've finished all the levels for Angry Birds HD. Will these achievements unlock when I boot up the game, or will I need to go through the whole game again? I'd try it out myself, but I'm stuck at work for another 4 hours.
Thanks for the quick reply! Hmm, so it just depends on the game. Too bad, but I guess it's better than a straight "no".
