I don't really think that there is a "child-friendly" camera phone. If you are going to get your child a phone, it should NOT be a camera phone. They are extremly expensive & difficult to replace. If you are planning on getting a young child a phone, you might want to consider Verizon's child-friendly Migo phone. Or Cingular's Firefly. Both these phones were designed for young children and let you control how your child uses his or her phone.
Dont get the migo or firefly they dont sell those anymore! get a razr for kids
