Earlier in the month we shared a rumor that the Nexus 5 might launch alongside a new LTE-equipped Nexus 4. There is some new intel out today which supports this theory. A new Bluetooth certification was just passed for a device called the LG E960. That's the same model number as the Nexus 4. The only difference is that this one includes LTE onboard now.
It's actually not too surprising that Google is doing this because the Nexus 4 actually already had the LTE tech hiding disabled inside. In fact, you could easily argue that it was more surprising that Google didn't have it already enabled to begin with.
