Unlocked

Good point.

AshHall:

What do you mean by "unlock"? There's 3 kinds of device locking.

1) Carrier lock: How to unlock your iPhone for use with a different carrier - http://support.apple.com/HT201328 - Only some carriers offer the ability to unlock iPhone for use on any carrier. Follow the instructions in this article to unlock your iPhone.

2) iCloud: Activation Lock - http://support.apple.com/kb/PH13695 - This is a security feature so only legitimate (i.e., not stolen) redistribution of devices is possible. See: Turn off Find My iPhone Activation Lock - https://support.apple.com/HT201441 - If an activation lock was put on a device, only the owner of the account that applied the lock can remove it. Get them to remove it or return the item for a refund.

3) Device lock: If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled - https://support.apple.com/HT204306

Unlocked from what? Forgot passcode? Carrier lock? Activation lock?

Read the Apple Support document about what to do if you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled. Click here --> http://support.apple.com/HT204306

At the very end of the document it mentions briefly about possibly seeing a request for your Apple ID account information to do this. In order to keep this reply to the point and brief I won't post about strings of eventualities, so post back if you encounter problems should you need to do that.
