Unfortunately for both iPhone third-party developers and Apple, the FairPlay DRM that protects apps was and pirates have been using cracked versions of paid applications for a while now.

As of yet Apple has shown no signs of trying to curb this rampant piracy. This lack of response has prompted some developers, such as Ben Chatelain, to take matters into their own hands.

Chatelain recently released version 1.1 of his US$1 application . Having noticed a dramatic rise in illegitimate use of his app after a cracked version was released on a piracy site, he decided to try to fight back and perhaps even convince some people to buy the program. So he  that checks whether or not the application has been legitimately purchased. If not, the program waits 10 launches and then puts up a message asking the user to either quit the application or purchase it from the App Store.

On the off chance that the application starts harassing users who've purchased it legitimately or even just in case users take issue with the fact that the application "phones home," the developer has made sure that this functionality can be remotely disabled.

Although this is one of the first examples of a developer actually having implemented anti-piracy measures in their application, other developers have already been talking about this issue for a while now, , the developer of iPhone application . So far, Chatelain's , with five of the 39 who've gotten the message opting to buy the application.
