Sent my form in about 2 months ago,received email saying to ring customer services because my account in now closed.Spoke to customer services for about 30 min.Was told i would receive unlock code within 48 hours.....over 1 month later still waiting.Any suggestions on what to do now?
There is not in fact an unlock code for the iPhone.
Once Apple have completed Vodafone's request to unlock the phone you need to insert a non-Vodafone sim card in the phone and then connect to iTunes. If it has been unlocked you will see a mesage in iTunes telling you so.
Try the above as it is possible that the phone is already unlocked by waiting for you to complete the process by connecting to iTunes.
