    Using my Cingular GSM while on a Cingular network is rather straight-forward and works well.

    There is a username and password that is used to log into the Cingular network. Now come the question about how this works when we are roaming. Say I'm in London or France on the Orange network or some other network. Does this DUN ability still function (without change) or will I need passwords for those carriers? I have used my Treo in England and France using my Cingular SIM without problems. I have even used email and data. But what about DUNing?

    Actually, this question is relevant to roaming in the U.S., on other carriers, as well.
