I own two unlocked devices that were purchased at full-retail price from Apple. I have restored them both with the latest updates (10.3.1) and I never received the notifications saying "Your iPhone is unlocked!" This happened on both devices. I do a full wipe and restore every software update that comes out (Crazy? Probably.) and this is the first time that I have not received the message. I called and spoke with Apple Support earlier and they verified that both devices are shown as unlocked. Has anyone else noticed the same thing with 10.3.1?
