An LG device named the "LG-D820" has shown up in a Federal Communications Commission (FCC) regulatory filing. It has a 4.96-inch display, wireless Qi charging, and, oh yeah, it runs KitKat.

The listing, which was first spotted by s4gru.com, shows a back case that is a dead ringer for the Nexus phone that accidentally showed up in Google's KitKat Android statue unveiling. The shapes match, the case has a hole for the distinctly humongous camera lens, and the flash location lines up. The "M8974A" firmware indicates that this bad boy is sporting a Snapdragon 800. The Nexus 4 was closely based on the LG Optimus G, so I would expect this probable new Nexus to closely resemble the G2 internally, especially considering the matching SoCs. And just like the G2, the battery and back are nonremovable.

The next big question is carrier compatibility. The D820 is packing LTE bands for AT&T, Sprint, and T-Mobile (bands 2, 4, 5, 17, 25, 26, and 41), along with pentaband DC-HSPA+, quadband GSM/EDGE, and CDMA/EVDO rev A. Despite the CDMA and EVDO, the phone is not compatible with Verizon's LTE, which would need band 13. For local connectivity there's 802.11b/g/n/ac with 5GHz support, Bluetooth 4, and NFC.

If there was any doubt that this was truly a Nexus device, the software listing of "aosp_hammerhead-userdebugKyeLimePieFACTORYeng.sangjoon84.lee.20130618.015154" should settle it. The oddly spelled "KyeLimePie" would be the software version (think: KitKat), and the "hammerhead" device codename fits in perfectly with the other recent Nexus code names of "Tuna" (the Galaxy Nexus), "Mako" (the N4), and "Grouper" (the 2012 N7). The only question is the final name: Nexus 4(.96) or Nexus 5?
