Playing Games Without Sore Thumbs January 10, 2012, 9:33 pm LAS VEGAS - The electronics casemaker Speck has rolled out an iPhone cover that is supposedly kind to the thumbs. The new CandyShell Grip is an iPhone case designed especially with gamers in mind, adding soft-finned grips so that Doodle Jump fiends and other game aficionados won't suffer fatigue no matter how many levels they clear. The case is made of a glossy hard polycarbonate shell with a rubber lining to protect the phone from knocks. That same soft rubber is placed strategically where thumbs and fingers rest when hard at play. The raised fins allow ventilation in case the action is intense enough to moisten your grip. The case come in black, yellow, red and white and is available through Speck for $35. While the case may help your game, there is no guarantee that it will save you from the dreaded "Blackberry Thumb," so you may want to put the games away once in a while, no matter how confortable your fingers may feel.
