AT&T told us back in July that it was fixing to launch the first carrier-provided two factor encryption service, and it seems that today's the day. The day it goes live, we mean. At any rate, the company's Encrypted Mobile Voice service is reportedly active, and it's already providing "high-level security features for calls on the AT&T wireless network." Of course, none of this fancy security is meant for simpletons like us -- instead, it's targeting government agencies, law enforcement organizations, financial services institutions and international businesses. We're told that the tech combines KoolSpan's TrustChip and SRA International's One Vault Voice, with the former being a microSD card and the latter being a software layer. Currently, it only plays nice with BlackBerry and Windows Phones, but until we see Biden bust out a Bravo, we'll assume the lack of Android support isn't "a big flipping deal."
