But it's pretty simple. You ask your carrier for the code and if you've paid off the phone, they give it to you.
Sprint, CDMA versions are NOT UNLOCKED WITH CODES. I decline to repeat how those differ.
I look on youtube an would like to know can someone point me in the right direction on how to unlock my iPhone I would like to change to a different carrier. anything free, free, free, out there to do it. thanks for the help. I have sprint.
