CHICAGO (BBC): A smartphone designed for handling top secret communications has been developed by Boeing. If the phone is tampered with, it automatically deletes any data and renders itself inoperable. Better known for its aeroplanes, the firm said it needed to help organisations get “trusted access to data to accomplish their missions”. The device, named Black, joins a growing range of high-security smartphones entering the market.

At the Mobile World Congress in Barcelona, a similarly-titled Blackphone was announced, aimed more at businesses and consumers worried about private data.
