Been perusing them for a bit. Not having much luck implementing for the moment. I think that is because I didn't have a sim in the phone. It's not a big issue to me at the moment. As a backup phone I don't actually need to unlock if I go with AT&T or even if I switch it to Straight Talk. Of course, it would need to be unlocked to use other prepaid options. Anyway, I subscribed to the threads I will revisit when necessary.
