The LG Eclipse specifications may still be placed in the rumor category, but the network it's going to be on is now a matter of public record, as the phone has popped up at the FCC's website today. What we now know for certain is that the phone will be CDMA/EVDO/LTE capable, using Sprint's bands; along with the standard stuff like GPS, Bluetooth, and Wifi (dual-band 2.4 and 5GHz style). The LTE radio operating in the 1900MHz band locks this one as a Sprint LTE exclusive, though we wouldn't rule out LG making something very similar for Verizon or AT&T.
Why anyone would want this to hit their carrier is explained by the rumored specs. Supposedly the Eclipse will be sporting a quad-core Qualcomm S4 Krait, and 2GB of RAM. These specs (and again, there's nothing concrete about them just yet) would make it the winner of the coveted Android monster-spec'ed phone crown. In short, Imagine a Galaxy S 3 (Galaxy S III) with two times the CPU power.
Of course, software matters. If this one ships with anything short of Jelly Bean (it's rumored for a Q4 appearance) hardware geeks across the Internet will go completely ballistic -- and we will, too. Ball's in your court LG and Sprint. We want you to hit us with a ton of WOW factor here in both the hardware and the software side.
