From my point of view and with my rather poor knowledge of iOS, the principle of a sandbox in iOS is the following:

  • each app and its data is installed in a private area within the partition, but each app runs under the same user 'mobile'
  • the sandbox only allows restricted and controlled access to system ressources (i.e. system files)
  • the sandbox only allows restricted and controlled access to ressources like contacts, sms, mail, internet...
  • the sandbox prevents an application from attacking another application's data

Are there any important functions of the sandbox that I left out?

I assume that with a jailbroken device, all security functions of the sandbox are obsolete (i.e. an attacker can easily read data from other applications, can access system files etc)?

If jailbreaks work similar to android, normal applications will still be sandboxed. But of course the user/owner of the phone and applications authorized by him can access everything. But that shouldn't be a problem, since the purpose of the sandbox is to protect against applications, not against the user. –  CodesInChaos Feb 13 '12 at 22:02
    
But I guess it's also a function of the sandbox to protect application's data from beeing accessed by malicious applications (i.e. trojans). This protections doesn't work anymore on jailbroken devices, isn't it? –  pfust75 Feb 14 '12 at 7:37

Your assumption is correct, with one limiting factor: any encrypted content can only be accessed when iOS has been unlocked, even when jailbroken. It's not much of a limit, but there it is.
