I've experimented with urethane film before to keep my iPhone screen protected and no matter how hard I try (special tools, etc) I always seem to get bubbles between my phone and the plastic — talk about frustrating! After coming across the Invisible Shield booth at Macworld, I've decided to give it another shot. As you'll hear in the video below, this film was originally used to protect the edges of military helicopter blades, making it virtually scratch proof. Bubbles aside, you can't help but think this material would do an iPod or cell phone good. And best of all, if your Invisible Shield ever becomes scratched or otherwise damaged while protecting your device, they will replace it for free. Would you ever use something like this to protect your devices?
