Earlier today, an unannounced Sony smartphone passed through the United States of America’s official certification authority — the FCC. Information included in the filing documentation reveals that we could possibly be looking at Sony’s upcoming Xperia Z3 (D6603) — a revamped model of the company’s flagship smartphone of 2014.

Unfortunately, the paperwork doesn’t disclose anything about the internals of the device, but we do know that the handset is set to pack a variety of different connectivity options, including support for 4G LTE carrier bands (4,7 and 13), Bluetooth Class 1 (Version 4.0, LE+EDR), 802.11b/802.11g/802.11n Wi-Fi, NFC and GPS.

What’s particularly unusual about this filing, is that Sony rarely authenticates its devices for distribution in the U.S.  before it officially announces them, the United States is traditionally one of the later markets to see Sony’s latest smartphone releases — so it’s clear that the Japanese company has big plans for its next flagship device with regards to its international release.
