Little kids, big kids and kids at heart will find entertainment in the Brick Case for iPhone 4. Like any other skin, the case simply slips over the phone to provide protection from nicks and dings. However, this case also features a grid of nubs that allow Legos to connect directly to the case. Finally, a way for iPhone to provide some non-tech entertainment! The cases are available in white, black or clear and retail for just $20.
