Party, mate! We had our app pirated a few weeks ago, it didn't have any impact on the sales. People who pirate your app wouldn't buy it anyway I imagine. Unless it was really well-known and great - but then there's no chance of it not being pirated. You can verify if the device is jailbroken, but as @wccrawford said couple of comments below - they might have paid for it. And I know many people using jailbroken devices and not pirating one thing. Party! Your app was deemed worth pirating.
