So I was working on giving my iPhone 4 away and I needed to unlock it. I contacted the carrier and all the proper directions were followed. With the request submitted and processed I restored the iPhone and waited for iTunes to tell me that the phone was unlocked.
I never got the notification.
After some research it seems that Apple simply says that after the unlocking procedure is complete you simply need to Erase All Content & Setting in order to complete the upgrade. Now my question is thus: Is the unlock process done during the activation portion of the start up sequence?
