Hi all, Had an iPhone 4 and recently purchased an iPhone 5 on a new contract. The iPhone 4 still has it's own number, and I'm using a new one all together. Logged in with my AppleID so now imessage is assigned to both phones and both numbers. I've restored the old phone to factory defaults as I'm selling it, and will give the sim to my wife for her Windows phone. I've been into settings on the iPhone 5 and unticked the old number in the messages section. How do I remove it completely? It's bugging me being in there. Tried logging into my Apple account online to unregister the old phone, but all I see is my iPhone 5 and iPad. The iPhone 4 is not listed. any ideas?
