content: I have one of these, it's a buggy piece of junk, and I don't trust their security at all. The silent* stuff is good, but the blackphone itself has problems, as does their support.  They're going after the enterprise gap left by blackberry, so it's not really a consumer phone, and they're not fixing the non-silent* bugs. Though I agree we need more common uses of encryption.  I look forward to the day I can buy a bare-metal phone and bootstrap it myself.
