Guys, come on here. It's not like apple is against jailbreaking or open development because it's going to destroy the product and they don't want to warranty it (like desoldering components are ripping apart your engine block would), it's that it will disrupt their business model. Why can't I get a grooveshark app without jailbreaking? Is that going to physically break my iPhone? No, it's going to let grooveshark encroach on apple's bottom line.
