Again. Your hope is misplaced. This will never happen. In case you missed all the posts above yours, there is NO DOMESTIC UNLOCK.I would love if someone posts a video of a T-mobile or AT&T sim being used in a Sprint iPhone 6 or 6+ bought at the apple store at full price.
You can hope all you want, but it's never going to happen. It's been explained several times over to you now. And Youtube videos are NOT proof. ANYONE can fake a YT video! The ONLY unlock we are currently discussing is an INTERNATIONAL unlock.
But go ahead. Ignore what I and others in this thread have said ad nauseum if you want. In the end you will find we were right no matter how much you don't want to believe us or how hard you try to ignore the truth.
