It is NOT illegal to hack this. It will certainly void your, warranty, but you paid for the iPhone/Pod, so you can do whatever you want with it. However, performing illegal actions with it, such as emulators, is illegal. There is nothing the law can do about it, it is just against the terms of your warranty. If this was in fact illegal, Apple would have already gone after developers such as Redsn0w. Don't you think if we can access that information, Apple could too? Common sense is wonderful thing to have.
