1,5 years ago I bought a new iphone 5 over the internet. When I now tried to replace it with a new one in the Apple store they told me that my phone was originally a Verizon phone and apparently someone has unlocked it (for other sim uses). The problem I am now facing is, that they would be willing to replace it, however, apparently in the system it says that my phone is still locked. Hence, even if they give me a new Verizon phone it will apparently still be locked and I might not be able to use it in Germany.
Now I am not quite sure (and they couldn't tell me in the apple store) what it actually means if the phone is locked - does it only refer to sim lock or is there also another type of locking the phone?
In either way, could anybody please help me out on how I go about unlocking the new phone?
