That's certainly technically possible to achieve both security and "hack-ability", but having a reasonably attractive business model and user experience to make it available for general public is another layer of challenge. The analogy of apartment is interesting, as today people may have equal or more to lose on a cellphone breach comparing to apartment, while managing the security is much more difficult on cellphone for common users. That fact certainly contributes to the prospers of walled garden (apartment management company) like Apple. btw thanks for all the great work, saurik. //hatoff
