My cell number shows as "unknown" on my iPad 3(AT
When I purchased my iPad 3, I used the cloud to back from my previous iPad - an iPad 2. I think this has caused problems with my cellular account. Specifically, when I go to About section of Settings, the cell number now shows as "unknown". When I logged into my AT&T account from the iPad 3, the number shown was the same as the number for my iPad 2, which I obtained in the About section of Settings. Any ideas?
iPad, iOS 5.1.1, AT&T
