    With all (perhaps only one) the baseband downgrader utilities in Cydia, I never really downgraded anything but just installed Ultrasn0w after jailbreaking my 3g iphone that is 3.0 firmware.

    I'm travelling tomorrow and I don't want to get caught off guard when I pop the country's sim card in and it doesn't work.

    Any surefire way to tell if Ultrasn0w will definitely work without actually having another sim card on hand?

    If another SIM card works with your phone other than the official carrier's SIM, then UltraSn0w is working.

    Put a T-Mobile SIM card in your phone and see if it works.

    guys I said, without having a sim card, is there a way to tell if it's going to work.

    I guess the question is, do I need to downgrade the baseband?

    No you don't.

    If you did everything right it will work. The acid test will be when you get there - unless you have friends here on a different network, and can just pop their SIM in as a test.

    No. Just ask one of your friends with T-Mobile if you can test it in your iPhone.
