withstand anything you throw its way? Dip it in sub-zero temperatures, bang it against concrete, drop it from great heights, and then stand on it? That was the full extent of our imagination today when getting to grips with the Sonim XP3300 Force and the damn thing didn't budge a millimeter, never mind an inch. It has a Gorilla Glass-protected screen and some rather self-apparent water- and impact-resistant hardware surrounding its soft electronic core. Changes in this latest model include the redesign of the Java-based OS, the internal power supply circuitry, the GPS module, and the antenna, all in the name of improving efficiency to a claimed 24 hours of talk time on a single charge. That's quite the feat, even if you can't exactly stream HD Flash videos using this chunky fella. The XP3300 Force is available in 50 countries around the world today, with pricing near $400 unsubsidized or between $50 and $150 on contract. Skip past the break for video of its endurance.
