Cydia guy, "saurik": not a pirate!
The pirate guys are smarter than you, have better tools, and are much more bored.
Phds love disassemblers.
Every minute spent on DRM is a minute you don't spend making your game more appealing to paying customers. 
IRC client: takes control of your system if you pirate it. Pirates *hate* that. They won't be your friends. 
Single "please don't pirate" nag screen, just once -> sales and eventually removed from piracy repos. Neat!
Think about your actual customers, like the top grossing screen. Pirates just aren't your customers. 
Ski jump got more blog reviews its first day than purchases. Funny!
Q. Do people crack free apps just to remove ads?
A. Yes, but we try to discourage them. (even cydia has ads) apps should try differentiating among priced versions as well. See Photoshop elements.

NOTE: you have to be really clever to do demos and things.
