For world travelers with a need for LTE speed, Samsung's newest version of the Galaxy S4 might be the answer to your jet-setting prayers. When they arrive, the updated Galaxy S4 and S4 Mini will be the world's first handsets to automatically switch between the two different types of LTE networks used worldwide. While FDD-LTE is the standard in most of the world, TDD-LTE is becoming more popular in countries around the world.

While ZTE introduced the first dual-mode LTE phone in China in late 2012, that handset required a not-so-seamless reboot to switch networks. Samsung claims its dual-mode S4 will allow continuous voice or data coverage even during format switchover. So globetrotters used to juggling a carry on full of burner phones or switching out SIM cards can spend that time doing more important things. Like playing Candy Crunch Saga. Samsung says the dual-mode phones will launch worldwide sometime in the third quarter of 2013. [ZDNet via Cnet]
