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 7.3.2, but nothing change in the end. I use the method iUnlock, apptapp, installyoutube.term and unlock with 20 minuts to go. And now i'm using my regular SIM. Not anymore the TurboSim.

Please, if anybody coul'd help me???? Or better anybody knows what is going on?????

Please, dudes help me!
