Yes, all these codenames for Android-versions can't be good for your teeth :).
Seriously, it's getting boring to know that after the version, we don't even have, gets a successor. Oh wait, still not even 2.2 is out for many phones. Thanks to their own rubbish they put on the great vanilla stock Android.
So we know the successor (Ice Cream) of the successor (Honeycomb) of the successor (Gingerbread) of the successor (Froyo).
Well, thanks for letting us know :).
