You can’t see them unless you are a registered iOS developer, however John Gruber has done an excellent job recapping it. Take a look at the points that he calls ‘interesting ones’.

Of note Apple is flat out saying that if your app is crap they will reject it, likewise if it is the same as 10,000 other apps without improving upon them. Really interesting is that the higher the price the more time they spend on it, which from a consumer stand point is really great.
