    Hi, I just received a replacement iPhone 4 for my old one which was defective. Problem is that I don't have AT&T anymore (and thus I do not have the sim card) and I'm not sure how to go about checking the firmware. Can anyone provide some insight? Thanks!

    Plug the iphone on your computer and run tinyumbrella.
    It will list its firmware and baseband installed.
