When i got my phone the call waiting worked just fine.
Were you in a different location? Some people have had trouble turning call waiting and forwarding on/off if they are off-network.
The iPhone plan does not come with what's called "off-network alpha tag," so there is no way to tell if you are on an AT&T partner network (yes, this happens in various parts of the US) unless you call CS and ask that it be activated (free). Without the tag your phone always dispays "AT&T" for network. With it you will see "Off-Network" when you are off.
Sometimes even with the tag I find it hard to tell exactly when I'm on/off if I am between two towers, one AT&T and the other a partner. So if you are on a "border" between networks, try moving to known AT&T ground and try again. One kludgy way to tell without the tag is to call 611. If you are off-net you will get a recording telling you to dial the 800 number instead.
