As if Las Vegas didn't have enough problems to already worry about. With the lackluster economy making the tourism industry go in a funk coupled with the fact that people don't have enough to pay their mortgages let alone gamble, "Sin City" now is faced with yet another weapon: The iPhone.

A new application on the iPhone has pit bosses worried silly over the ease of counting cards from Apple's handy device. The New York Post writes:

Call it "iCheating."

Nevada gambling regulators have warned casinos across the state about a card-counting program on iPhones that can illegally help players beat the house at blackjack, officials said.

The Nevada Gaming Control Board warned casinos of the program after learning of the Apple phone's function from California gambling regulators who said officials at an Indian casino found customers using it.

"The program calculates the true count and does it significantly more accurately," according to a Gaming Control Board memo sent to casino operators last week.

Card counting can help blackjack players determine when they are likely to win a hand and should adjust their bets.

The mathematical technique is most commonly used to gain a statistical edge over casinos as a player mentally recalls cards that have been exposed and assign a set probability value to the remaining cards.

Although the practice is not illegal in Nevada, using a device to count cards is considered a felony, officials said.

Still interested in the application despite the fact that it is nearly impossible to find a single deck or double deck game of blackjack in Vegas (where card counting comes into play), the fact that pit bosses already know about it, and that it is a felony if you get caught using a device to count cards? The application is called "Card Counter" and costs $2.99. You can download it on iTunes.
