Silent Circle, the company behind the security-focused Blackphone, has released the latest version of its SilentOS, which now includes a Privacy Tracker feature to detect flaws in the device.
The Blackphone - a device with a customized version of Android 4.4 that offers "unparalleled" privacy and claims to keep users "off the grid" - is now shipping to buyers that pre-ordered it for $629.
Blackphone, the security-theme Android smartphone that was first revealed last month, is now available for pre-order for the unlocked price of $629. It's due for release in June.
Two companies, Silent Circle and Geeksphone, have announced plans to release the Android-based Blackphone, which they claim will offer more security and privacy than regular handsets.
