Tunewear (http://www.tunewear.com) has released the GameHandle for
the iPhone 3G, iPhone 3GS and second gen iPod touch. The US$19.95
device is designed to provide a better grip on the Apple devices when
playing action and racing games.

It has a rubber coating on the surface that Tunewear claims is
comfortable and feels great to the touch. It also prevents your hands
from slipping when you’re game playing.

An internal sound cavity system resonates the sound from iPhone or
iPod speakers inside the GameHandle body. It outputs the sound
through vents on the back for an overall improved audio experience.
