This is a cool idea:
Silent Circle and Geeksphone have partnered to combine best-of-breed hardware with all the skills and experience necessary to offer BLACKPHONE - a privacy enabled mobile phone.
It's built on the Android platform, which is very insecure, completely fragmented, full of bugs, and own by Google, the defacto anti-privacy-we-collect-all-your-data-and sell-it company.
Silent Circle apps are great. The company has some top crypto and security guys on it, however... Android? Seriously?
It is a good idea. Not on Android though.
