How do I change the phone number for IM and FaceTime?

Question

Since my update to IOS 6 my FaceTime and IM are using my wife's phone number and I can't change it to mine. The email address are editable but the phone number is not. Help?

Answer 1

All of my devises are updated to iOS6. But after reading your reply I tried turning off iM and face time in all three devices, powered them all down for 10 minutes. I turned my phone back on first (the one I wanted associated with my iPad) then turned on my iPad. I turned on iM and face time on my phone, then the iPad. In came up with all my info including my (correct number) phone number. Then I turned on my wife's phone and turned her iM and FaceTime on. Her number also popped up in the iPad but I could choose what number I wanted to use and left hers off. Her phone number is associated with my iTunes acc because we share all of our music and apps. For a little privacy you'll have to make a separate iTunes acc to completely get the unwanted number off the iPad. As long as both numbers are there you can switch between phone numbers and see iM messaging.
So basically the phone numbers in the iPad are edited thru the individual phones, iTunes acc and not the iPad itself.
Hope this helped if you're having the same issue.
