The new iPhone 4 loses signal when held by a human hand. I hate to admit it but its true! The iHand ($69; the end of July) is designed to easily let you receive and make calls on your iPhone 4 without experiencing any signal drop. Just insert iPhone 4 into iHand’s adjustable fingers, raise it to your ear and start talking.
"Featuring Apple’s unibody design, iHand is precision-carved from a single piece of European beechwood. So it’s lighter than a standard medical prosthesis, yet 12x stronger. You can grip iHand either of two ways: by placing your fingers around its palm, or by grasping the aluminized Extender that telescopes from the wrist socket."
