Now the iPhone is attractive to kids too.
Japan-based Mobile Art Lab has taken iPhone innovation in a new, more kid-friendly direction with the introduction of the PhoneBook.
The software and book-like construct combination offers a child and parent the opportunity to read interactive stories or learn simple math lessons together.
The user simply loads the iPhone software up, slides the iPhone into the book holder slot and the interactive learning can begin. You can check out video of the PhoneBook in action here.
