    Hi there,

    I've read about the method to unlock 5.15.04 which is to upgrade to iPad BB and downgrade it to 5.13.04.

    I would like to unlock my iPhone 3GS. The iOS now is 5.0.1 with BB 5.15.04

    What is the steps/procedure that i need to follow in order to unlock it to be use on any telco carrier?

    Thank you

    Btw, right now the 3GS is already jailbroken. I used the SAM method to unlock for my SIM card. But now, i'm going to pass this phone to my brother which has his own SIM card. As far as I know, SAM method has been patched and cannot be use anymore...

    Thus im relying on the Upgrade and Downgrade BB method to unlock for him

    I recommend you buy the IMEI unlock instead play around with this.... special it is only few buck and it will be very well few buck you ever spend on iphone.
