    O.K. fine, I am stupid,but I honestly don't remember if I bought the thing locked or unlocked. ATT/Cingular is totally unhelpful. I would like to do a firmware upgrade. My firmware is 01.05 and the Software says Treo650-1.04-CNB. What can I upgrade to and where do I get it. Thanks.

    The only way to tell if your phone is unlocked is to try using another carrier's SIM in it. You've got Cingular Blue software on it now...there is no Cingular-branded update available at this time, but you can apply the Palmone 1.28 update for the unbranded, unlocked Treo 650 - if you first apply the 1.21 or 1.23 beta updates (available in the forums, here).
