So I got my iPhone 5, when I did I got it from another provider and backed up all the data from my iPhone 4. Because of this the iPhone 5 came with it's own number however I'm currently in the process of getting my number transferred to my new provider for my iPhone. My iPhone 5 now though has 2 phone numbers it receives iMessages off, I want to delete the phone number my iPhone 5 came with but it won't let me (it's shaded out and won't let me un click it). To make matters worse on my iTunes account I don't have any mobile numbers listed so I can't do it from there either. So any ideas?, I don't want to use the new number I have been given and I don't want to get iMessages from random people once the number has been reassigned to someone else. I have been able unclick on that number for my Macbook Pro, but on both my iPhone 4 and iPhone 5 I cannot delete that number from receiving iMessages.
