Game Gripper. You make smartphone gaming a rather less cramping experience, and now you're spreading joy to the fourth generation. Owners of Sprint Epic 4G can now get their Gripper on, and can do so with a lovely new Genesis-inspired layout that offers two rows of three buttons plus a D-pad -- and then another four buttons for good measure. It's rather excitedly demonstrated after the break and, like the earlier models, will set you back $14.99. Now, if only we could get handset makers to start adding shoulder buttons on their cellies.
