Yes, although not when it diminishes other people's fun with the product. For example, use a Modded controller to own at COD's campaign, but don't use it in multiplayer, 'cos that's just cheating.
Or in real life, buy as many guns as the law allows, but don't shoot anyone, because that'd be really mean.
For things like jailbreaking, I can see why the manufacturers wouldn't want you to do it, but legally, you should be able to, as long as you're willing to accept voiding the warranty etc.
