The LG G Flex, which recently went on sale at select few retail outlets (Negri Electronics in the US), is yet to arrive on carriers. It has already been confirmed that the first generation curved Smartphone is headed for AT&T. Now, Sprint users have something to cheer about as well, since the LG G Flex recently passed through the FCC, certified for Sprint's LTE bands (800/1900/2500). Don't expect to see the device go on sale just yet, this could take another month at the very least. Even then, carriers must be wondering how much upfront price to ask for considering that an unlocked G Flex costs North of $1000.
