[UPDATE: Erica Sadun of Ars Technica weighs in on Crackulous, and the humor of pirating pirate software... - Rene]
Let me start out by saying none of us here at TiPb condone any type of piracy. You think you deserve to get paid at the end of the day for your work? So do developers and their hungry children.
That being said, Apple must be saying Uh-Oh right about now. Crackulous, which is now available via Cydia, enables you to strip the protection off most apps from the App Store. What this simply means is if a single person purchases an app, he or she can put the app out there -- for free -- for anyone who has a Jailbroken iPhone to grab.
Of course, it was simply a matter of time before someone in the Jailbreak community came up with an app such as Crackulous, and we can just imagine how many new Jailbreak artists there will be because of this new app.
You can pretty much count on the fact that Apple is already addressing this issue with a FairPlay (their DRM that wraps all iTunes App Store apps) fix that will turn up in the next software update. Another cat and mouse game has just been born.
