Phil Zimmerman's post-PGP Silent Circle: Privacy for $20

I have so many technical questions about his software. How does he plan on implementing this in iOS? It is difficult to modify the Phone app, and impossible without a jailbreak. Is this going to be a separate app for phone calls and emails?

And on top of all these technical limitation imposed by Apple, will this service only work if both parties (you and the recipient) have this software installed? This will prevent widespread adoption.

You don't modify the Phone app. You build a custom VoIP app like Skype did.

And yes, it can only work if both parties have the app installed. Otherwise, someone along the way (at the tower (your mobile provider) or in the OS (Apple)) will have to decrypt the data for you and that sorta defeats the purpose.

Actually, no, it can work when only one person has the app installed, albeit without end-to-end encryption.

> If only one person has the app, the connection will be scrambled only to Silent Circle's servers, which could still be valuable for overseas users worried less about the FBI and more about their own government eavesdroppers.
