After months of anticipation, Apple may finally be on the verge of releasing its HomePod smart speaker. Earlier today we reported that clues along the Apple supply line suggest that the device might ship in February, and this afternoon word dropped that Apple had finally gained approval from the US Federal Communications Commission (FCC) for the device.

In the official FCC filing, the device is referred to as the "Apple Inc. Wireless Speaker," with a code name of A1639. Accompanying product diagrams almost certainly confirm that it's the same device that we've seen discussed since June of last year.
