I have to say AT&T usually gets the best phones. Today we notice that the LG G Flex went through the FCC with AT&T friendly bands. We see from the report the model number is LG D959. Also it reveals Quad band GSM support, Bluetooth 4.0, NFC, GPS, and 802.11 a/b/g/n/ac WiFi. All the usual boring stuff. I know for sure when that lands on U.S. shores I will be grabbing that thing.
