In Texas Hold'em, go to the Options menu, and select New Player. Enter the cheat code as a new player name using the letter selection tool. Once the cheat code is entered, the iPod will jump to the check mark (done) character. At this point, you must hold down the center button until the code activates, and you'll see the word Secret appear on screen. For YOUCHEAT, you activate a secret menu that gives you five options, listed next to the YOUCHEAT password.
