So here's a great situation.... Currently happening to a friend of mine.
Her boss has an iPhone. It broke and was replaced (in NZ) under Apples repair program. No problems so far. Boss goes to Europe, puts in his local SIM (He travels a lot there). Phone complains that it's locked.
No, that can't be the case, iPhones supplied for VF in NZ aren't locked are they? Well... It's not that simple.
Sometimes the replacements Apple supplies ARE in fact locked... But surely you could just use the VF unlock page thingy? Well, If the VF system believed the IMEI was from a locked phone then yes, that might work. Does VF believe the replacement phone is locked? The people do, but their systems don't.
Resolution? There doesn't seem to be one.
Currently "Buy new phone" seems the easiest.
(On the other hand if someone actually knows how to sort this quickly, it would be much appreciated)
