Silent Circle's Blackphone:- The World's Most Secure Solution in Mobile Privacy.

The Blackphone, a privacy and security focused encrypted Smartphone from Silent Circle and Spanish Smartphone maker Geeksphone was announced today at the Mobile World Congress expo in Barcelona.
The Blackphone handset, which is being unveiled at the event, goes on sale in June for $629.

It works on a fully security-hardened version of of Android called PrivatOS and is pre-installed with lots of privacy-enabled applications such as secure calling and text messaging, encrypted file transfer and video chat.
The communications functions will be based on technology from Silent Circle, a U.S. provider of secure messaging co-founded by a respected Cryptographer Phil Zimmermann, best known as the creator of Pretty Good Privacy (PGP), which is a widely used email encryption software.
It has a 4.7-inch HD IPS display, a 2GHz quad-core processor, 16GB of storage, an 8-megapixel camera, LTE connectivity.

There is also a Wi-Fi connection manager for greater security on public networks, and a software that makes it possible to securely remote-wipe your device, and facilitate its recovery.Plus bundled in your cost of device are two years of Silent Circle, two years of Disconnect (secure/non-trackable search), two years of SpiderOak (secure cloud storage), unlimited use of Kismet (Wi-Fi analyzer product), and some gift subscriptions to Silent Circle so that your friends and family won’t have to sign up separately to talk with you.
Mike Janke, co-founder and CEO of Silent Circle told Mashable, "If you are on the terrorist wanted list or a criminal, intelligence services will get into your device. There's no such thing as 100% secure phone as Blackphone cannot mask metadata entirely from NSA.
