Where there's smoke, there's fire and by the looks of this latest FCC filing, LG's LS970 is all but a lock for Sprint's LTE lineup. Rumored to bow on that carrier as the Eclipse, the heavyweight handset, allegedly outfitted with a quad-core Krait processor, companion Adreno 320 GPU and 2GB RAM, has already been the subject of several leaks, leaving little of its spec load to the imagination. And now with the outing of these Commission docs, we can confirm that this uberphone does indeed pack 3G/4G radios tailored for the Hesse-led operator (CDMA 820 / 850 / 1900; LTE Band 25), as well as support for NFC, Bluetooth 4.0, WiFi a/b/g/n, GPS and SVLTE (simultaneous voice and data). While we can't be exactly sure as to its actual screen size, that reported 4.67-inch figure does appear likely given its 5.2 x 2.8 inch (130.9 x 71.6mm) dimensions. That's about all we were able to glean from the spate of included tests, but if you call Big Yellow your wireless home and are itching for a GS III alternative, this could be your next.
