Don't think so. App pirates are low life on the totem pole, and are arguably the biggest danger to the JB community there is. Why? App pirates cause app developers to put pressure on apple to make iPhone generations harder and harder to JB.
In the past and even now, JBing/is was possible, but we are seeing computer equipment bought by the masses that have been 100% resistant against attacks. The Sony PS3 comes to mind, as even after nearly five years, there has not been a single usable crack. App pirates push Apple to divert money from making cool things to locking down their products. If it weren't for app pirates, we all would have jailbroken iPhone 4gs by now because Apple would have spent more effort into other things.
Pirating apps is just pathetic. It isn't like iPhone apps are like Windows Mobile programs, where they cost $20-$50 a pop from Handango in the past with no way of knowing how good or bad the program is. The 99 cents or whatever the app costs ends up bettering the whole iOS ecosystem as a whole.
Just remember: When you look at your iPhone 4 with no Cydia, no lockscreen widgets, and no MiWi, thank the app pirates for this.
