Running subprocess in iOS?

Question

Is it possible to launch a new sub-process in iOS? (from regular application) If possible, how to do that?

Answer 1

While it may be possible with jailbreak apps, the SDK does not allow that. You are only allowed your own application's process. It can operate in the background (for a limited amount of time) and/or have however many threads of its own as you say, but they all have to belong to that one process.
