I have called Sprints 800 number several times and have been told that my phones are unlocked. I've gone to the Sprint store and they say they can't unlock my phones. I've called customer service from the Sprint store, they keep saying both phones are unlocked. I've reset the phones and tried to update PRL. The PRL update says I need to be registered with an account. I no longer have a Sprint account. How can I get these phones unlocked?
