    Default Unable to Unlock 1.1.1 with 04.03.13_G
    I recently bought AT&T iphone 8GB form US. I am unable to unlock it.
    Can you please help me.

    Thease are the steps i followed.
    1. Initially iphone was with 04.02.13_G
    Bymistake i upgraded to (1.1.3)04.03.13_G using itunes.
    2. I followed the tutorial to downgrade to 1.1.1 and successfully activated.
    3. But as modem firmware is 04.03.13_G, anysimv1.1 is not working to unlock.

    Can anybody help me in unlocking.

    Can we do the same on new iphone i.e. 16GB iphone?

    Sorry to say if your iPhone was originally 1.1.2 OTB then you won't be able to use software unlock... you'll need to go for a hardware solution such as next/turbo sim.

    I wouldn't continue trying to flash the phone with anySim as it'll damange your iPhone's phone capabilities.

    opening your delicate iphone, and if you are not 100% sure of what
    you're doing when you open your'll probably end up with a
