change icloud telephone number
I've bought an iPhone for the wife's birthday.
Of course I wanted to set everything up so she could use it straight out of the box.
I bought a prepaid simcard for this purpose and everything seemed to be working fine.
Created her Apple ID with her personal email address.
On her birthday she put in her own simcard and still everything seemed to be working fine.
iMessage works correctly - as well as everything else.
However... Settings/Messages/Send & Receive/You can be reached by iMessage at
Still shows that old telephone number - but it's greyed out.
Is there any way to get this deleted and get the new telephone number in here?
iPhone 4S, iOS 6
