Despite the Gorilla glass, we're not sure if it's a great idea to bring that iPhone to K2. Still, if you can fire it up, you can now make satellite calls from Apple's iPhone 4 and 4s handsets thanks to Thuraya's SatSleeve. Always-on globetrotter types can slip one of those models into a cradle, dial their pals from virtually anywhere via the company's own satellite network and even place emergency calls without the handset. The device also includes a built-in battery pack to stretch call times by charging your phone -- though given satellite rates, you may get charged more than you think. Thuraya said that an iPhone 5 version's also in the works, but if you're okay with Cupertino's prior models, hit the break for more.
