I am not sure why do anyone needs that.

You can have basically secure messaging on the phone today. You can use Replicant (libre software) on many phones where there probably are no backdoors, you can use OTR with Xabber (you can build it yourself), there are probably applications for PGP too.

Yeah, Replicant will fail to work on many phones and on those that work, half of the functionality is missing ( http://redmine.replicant.us/projects/replicant/wiki/Replican... ) - but trying to sell non-free phone as "secure" is snake-oil anyway. In my humble opinion.

Guy complaining that dropbox is useless because "For a Linux user, you can already build such a system yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem."

Yes, one can do all that but I think the market Blackphone is going for is the paranoid but less tech savvy crowd that wants a working solution out of the box. I am not saying this implementation is an actual working solution...
