I have perm root and S=OFF. Is my SIM unlocked? How can I tell? Is there a way to unlock SIM with root and then reverse back to stock and keep SIM unlocked? Im trying to unlock several phones and send them overseas. I just need to find a easy way to do this and keep the phone in stock condition if possible. Since I can only get 1 code from TMO every now and then, this wont help me.
