Griffin has introduced the Survivor Custom case ($50) for iPhone 4 and 4S. Like its predecessor Survivor, the Survivor Custom is constructed from a shatter-resistant polycarbonate frame and wrapped in silicone rubber, together meeting or exceeding Department of Defense ruggedization standards. It also comes equipped with a built-in screen protector and hinged plugs that seal the Dock Connector, headphone port, Hold Switch, and volume controls. Customization is a major feature, as the silicone wrap, shell and belt clip can be mixed and matched with numerous color options for no extra cost. Survivor Custom is available now from Griffin’s web site.
