Trendy Geek announced today that its film sleeve Pod Shield is now available in two sizes, large and small, fitting the new 20GB and 40GB fourth-generation iPods. The transparent Pod Shield helps keep the player’s screen and exterior clean and scratch free “without concealing its coolness.” It is made of a thin material that clings to the iPod using high-static. The front film covers the iPod’s screen, while the back film is designed to fully cover the stainless steel back and sides of the unit while still enabling users to place their iPod in a docking station. Pod Shields come in a three-pack for US$12.99.
