    A few days ago I unlocked my T-Mobile Bold 9700 and began using it with an AT&T sim card, everything was working fine until I hooked it up to the BB desktop software and updated it and now I can't get it to recognize either sim

    updating the OS will not relock a phone.

    make sure you go to a reputable unlocker, and upgrading or downgrading the OS will not re lock the phone/

    I agree with the others, re-installing OS will not re-lock your Blackberry.
    But, if none of the sim cards are working with your device maybe it's a physical issue with the sim slot...
