    I have a factory unlocked iphone4.
    Now I want to jailbreak it finally :)
    I got lot of threads discussing about the same; but got confused.
    Some forum say that my baseband should be 4.10.1 to jailbreak.

    My phone Software is 5.1.1 and Baseband 4.12.1; can I use RedSn0w to jailbreak my iphone.

    Thanks and sorry if it is duplicate thread; in that case you can give me a pointer to the other thread.

    Yes you can. Remember if you restore you'll lose the jailbreak.

    The baseband is needed to perform either a Gevey unlock or software unlock. Today the baseband is no longer an issue since AT&T and other IMEI unlocking services are available.

    Thanks.

    So once I jailbreak ; will I get the signal (carrier signal); or do I need to follow 112, airplane mode method to get the signal.

    Or do I need to install "Rocky raccoon" to get rid of this process. ( have done some research already :) )

    Please note that my iPhone is factory unlocked and I dont use Gevey Sim etc

    not enough research… :)

    You are close.

    Jailbreaking and unlocking are 2 seperate issues.
    Jailbreaking is gaining access to the phones file structure so you can install anything and mod your phone as you like. This is the firmware part; 5.1.1

    Unlocking is freeing your phone from use with just 1 carrier. That is the baseband part; 4.12.01

    As you stated you have a factory unlocked phone, you can use any carrier with it, stock or jailbroken doesn't affect that.

    Just use redsn0w to jailbreak, you don't have to install anything else to jailbreak it.

    Afterwards your phone will work as before, but with the jailbreak.

    Make sure you use TinyUmbrella to save your SHSH/APticket so you can restore or downgrade to 5.1.1 in the future when iOS 6 is out.
