Seems like an 'in development' version that was latent on the control servers, since you have to jailbreak and get the package through Cydia.
I know it's an old argument, but they don't have an attack vector and thus no known infection, because iOS is locked down, so only jail broken devices would be at risk. Say what you will against Apple's tight control over their ecosystem, but between keeping the NSA out of our phones data and things like that ineffective, it'll keep being a plus for me.
Most people assumed that the Apple encryption was designed in reaction to NSA intrusion into everybody's privacy. But it might also be a strong sales argument in markets where intrusion into people devices is just normal.
