The GranitePhone -- or in this case a Google Nexus 5 running the Granite Phone's operating system as it's being developed -- will arrive in the third quarter of 2015. It offers encrypted communications, including this e-mail service that only works with other Sikur software users.

If a contact uses Sikur's software a Granite Phone user will get an option for an encrypted call. Otherwise ordinary calls over the regular phone network are possible.

This is the back of the GranitePhone, but it's just an LG-built Nexus 5 development model for now. Sikur hasn't yet announced its GranitePhone manufacturing partner, but it'll be in Asia.
