I bought my mom and iPhone 4 yesterday, so she also got a new phone number. I deleted the her old contact information and created a new one. However, the old one still shows up when I want to send her a text, as well as the new one. Her info is correct in the Contacts app. Also, when she calls or texts me, it displays her whole phone number instead of "Mom".
I have tried everything I could think of to fix this, but to no avail.
