    Default iPhone 4 - Bad ESN
    I am pretty sure there must be many Bad ESN iPhone threads floating around, but I have a little different case. I am getting a absolutely brand new iPhone 4, but bad ESN, the phone has not been stolen or anything illegitimate associated with it. I am going to get it from U.S.A, it is of Sprint network, but I will need to use it in India(on Airtel network). Is there any way via which I can unlock it/flash it?

    Help is much appreciated. :-)
    Again, the bad ESN phone doesn't means something illegitimate is associated with it, I am just on a tight budget. And would love to have it in India!
    If there is nothing I can do, then I will probably tell my sibling to throw it in bin, and don't bring it to me here. :-(

    EDIT: Will doing this make it work?

    you have to find out, why does it have a bad esn? also does your india carrier use gsm or cdma? because esn is for cdma phones and imei is for gsm phones. if the phone with bad esn doesn't work here in the states, most likely it wont work in india either.

    No GSM iPhone 4 can have a bad ESN !

    is it GSM (uses simcard)
    or CDMA (doesn't have sim card slot)
    ?????????

    It is bad ESN for sure, that is, it is CDMA.
    Can you use my local Indian GSM operator on it using Gevey *?

    i remember reading that the ip 4s had dual-band CDMA/GSM chip but no sim tray. makes you wonder if a gsm ip4s can work on a cdma network?

    The iPhone 4 on Sprint DOES NOT have a sim card slot meaning you CANNOT use ANY gsm carrier with the phone/ Only the 4S have cdma/gsm capabilities, the iPhone 4 on sprint doesn't have a sim card slot

    the iphone 4s has a sim card slot on all carriers. unlocking in india is what you need to find out.

    Doesn't matter what he has, no Verizon or Sprint iPhone 4 (CDMA) can work with GSM. Only iPhone 4S (<-- that S is important) has any possibility at all of working with GSM.
