Okay, I wasn't really sure since they say AT&T / Unlocked.robk299 said:The phone doesn't need to be unlocked, just have no password.
I plan on resetting mine before sending because I don't trust them.
Also, as I found out earlier this year, you should delete the device from your Apple ID if you registered it or bought it from Apple using your Apple ID. That will save hassles later on if someone who acquires your device tries to call Apple for support, the serial number shows up as yours. Apple may assume the device is stolen and not provide service.
