Crackulous, a program for pirating apps from the iPhone App Store, was just released. Great for cheapskates, terrible for independent developers trying to make a living.
You'll need to jailbreak your phone to get in on the fun, obviously, but the entire process seems relatively simple if you're looking to get on board.
However, since many of these apps will need to phone home, they'll be letting Apple and the app makers know exactly who you are and what dirty deeds you're committing, right? There's a good chance nothing bad will happen to you, but you probably don't want to risk getting your phone locked down or your account shut off because you're too cheap to pay for Fieldrunners. Just give the developers the money they deserve, OK? [FunkySpaceMonkey via Hackulous]
