Call waiting won't turn on!

I had the same problem and after a 3 hour conference call involving myself, Apple and AT&T the problem was finally resolved. Turns out it was something wrong with a couple of settings at AT&T so you might want to contact your carrier and have them check your settings. I will say that the people from both Apple and AT&T were very patient, very thorough and diligent in the efforts to correct my problem. Good Luck!

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.
