So I got an iPhone 5 from the Apple Store last Sept on contract with Vodafone UK. Contract is up next month and I want to switch providers. So I used the VF webpage to request my iPhone to be unlocked and a few days later I got an email saying they couldn't unlock it and to contact them. Called them and they said it had to be unlocked by Apple. Went to Apple store and they say, nonsense, they can't unlock it, VF need to do it. After that, I remembered Apple swapped my handset a few days after I originally got it, so I think the problem is down to VF having a different IMEI number number attached to my account/contract. I found a VF page that said if the handset had been swapped by a third party then then they either have to unlock it or provide VF with the correct IMEI number for VF to do it. If the IMEI number doesn't match, I'm guessing thats why my original request with failed .. so how to do I get Apple to update VF with the correct IMEI number so I can get the darn thing unlocked?
