Hacked iPhone Application Data Security

If I am not mistaken (and if I am mistaken, here or in what I say below, please correct me), non-jailbroken iPhones provide two broad storage areas:

  • for applications (and data bundled with applications);
  • for user-managed files.

I understand that the former is a protected repository, which means that the data that is part of the application and stored in this area is not accessible to the user, except through the application.

On a jailbroken iPhone, does this protected area still exist? If so, what protective measures remain; that is, does it store data that is not yet accessible to the user?

On a jailbroken iPhone, the user has full access to all resources. The user will have more control over the device than any developer. You cannot hide secrets on the device, even available memory.

Even on a non-Jailbroken phone, it is easy to extract user data from the backups that iTunes creates when the user synchronizes (unless the user has enabled the "encrypt backups" option).

Applications themselves are encrypted using iTunes DRM, but since you can download applications to iTunes on your desktop and (AIUI), it’s easy to remove DRM, again, even users without malicious devices can access your resources.
