The HTC M8, following-up on last year's HTC One, has gained approval of US regulators on Thursday, before its supposed launch in March. 

No earth-shattering details about the handset were revealed through the FCC. However, it confirms the HTC M8 will feature soft, curved corners, and a design that will stick to the original HTC One. We pretty much knew all of those details from leaks, but hearing it again is always nice.

The HTC M8, expected to be called the HTC One when it's released, will be available in silver, black, and gold, if rumours and leaked press shots are to be believed. It will lose the first-generation HTC One's capacitive buttons for on-screen buttons, will feature dual-cameras for improved photography, and feature upgraded Sense 6.0 software on-top of Android 4.4 KitKat. 

The FCC filing mentioned word of AT&T-compatible LTE, but obviously, more carriers are planned. You can also expect NFC, Bluetooth 4.0, and dual-band 802.11ac WiFi. 

HTC will be holding a 25 March event where everything should become official.
