I called Cingular from my home phone (1-866-287-6131) per the number in this post:

I told them I was taking my wife to Italy for our anniversary and needed an unlock code. The guy's name was Greg (ask for him if you can!) and he gave it to me right way! I have an AT&T Treo 650 but want to use it with my Cingular SIM card.

That was my first call. Keep on trying until you get somebody nice!
