Restricted Messaging My daughter has an iphone and I would like to restrict when and who she can text with.  I'm aware that you can turn off the messaging completely but that's not wanted.  Is there a way to only allow texting to and from specific numbers.
You can't restrict Messages by person/number.  You can only turn Messages off or on.  This site can show you how to do that while using Restrictions to prevent your daughter from making changes.

There are some 3rd-party applications that might be able to do what you want.  Search the App Store for messaging apps that have that feature.
