iOS6 has loaded someone totally different's details I did an Over The Air update on my iPhone 4S this morning to IOS6. But it has showed me someone elses phone number after the update.

When I send an iMessage to my wife, it comes from this random persons phone number. When I try to facetime, it comes from this other number. But "Phone" shows the correct phone number:



^ This is the FaceTime setup. That is not my phone number. I have never seen that number in my life before.



^ This is the Phone set up. That is my phone number.

What's going on? How can I change this? Has someone else got my phone number and is getting my wifes messages?
