People, i have a big problem with my iphone.

I first use the TurboSim to unlock my iphone, so now i change for the software method and my iphone is not recognized my sim as a valid phone-network. His show me the signal only, the phone-network bised the signal is empty, but when i go to the "carrier" settings, appears the message "error" or show me one phone-network (not my), but not all phone-networks how show me before.

the most strange thing, is when i'm doing the unlock proceedier, i can see the phone-network beefore i finished the steps.

How can i resolve this, or better how can i restore the iphone in a lower level to erase all errors?
P.S: I do the normal erase by itunes, but nothing change in the end.

Please, if anybody coul'd help me????
