How do I detect that an SDK app is running on a jailbroken phone?
I'd like to be able to tell if a device is jailbroken. If it is, I want to stop my app, or at least warn the user that they may face untested and unstable situations.
Is this possible? How?
For the detection of piracy, check out this tutorial. It will allow you to detect whether or not your app is pirated. If your app is pirated, the user does not deserve to use it, so you could simply block them off — or at least give them a guilt-causing message. Note that all the credit for this goes to the author of the post - I'm just passing on the link for your convenience.
