How do I restrict calls to only people in contact list?
My daughter has gotten herself into quite a bit of trouble with who she's been talking / texting to and what she's been talking /texting about. She needs to have a phone so I just can't take the iphone 4 away from her. I have already disabled texting and safari, but Is there a way to restrict incoming and outgoing calls to people only listed in her contacts list? And is there a way to lock the contacts list? I could really use some information on this... and quick.
Thanks in advance for any and all help with this matter.
