    What is the baseband?
    Search on the internet for methods to unlock the iPhone

    since i have updated to 4.2.1 bb is 03.10.01 which is unable to unlock right now.

    but when i put the Sim it detects the Sim and one bar is visible in Antennae
    so actually i wanted to know if its factory unlocked or not.

    Or is there any other way to identify the factory unlocked Phone????

    To be certain that your phone is not sim-locked, you have to try 2 sim cards from different telephone providers.
    In your case, your sim card has not been rejected by the phone but you have a bad reception.
