Basically, I used to use cracked apps, lots of them. Those days are dead. I buy all of my apps now. Is there any way, whether in iTunes or some other program, to separate the cracked apps from the legal apps? I'm trying to free up space on my hard drive, and I'm sure I can knock out a few GBs by deleting all of my cracked apps. I have over 500 apps in my iTunes, and regardless of whether I use most of them or not, I don't want to unintentionally delete any apps I've legally bought.
