Thanks so much for your answer.Unlocking the Bootloader is different than unlocking the SIM. Unlocking the Bootloader allows you to install a custom recovery, root, and install custom ROM's. Unlocking a SIM allows you to use your phone on another carrier. In the U. S. carriers are required to that if you ask.
Boy I hope I said that right. I know just enough to be dangerous.
So what i need to do to unlock sim 1 and make it works with all networks ???
