No you don't because if you told the carrier your phone you jail broke your phone it could get bricked. Bricked means its deactivated and you can't use it anymore. Technically jailbreaking you phone is legal but if you buy any free apps with it then they brick you phone if they find out.
Jailbreaking a phone is partially legal and partially illegal. I have a post regarding this http://www.techlucid.com/2013/11/is-jailbreaking-illegal-or-not/
It is. The only problem is that it voids your warranty which means, if it breaks due to the jailbreaking, you won't get it fixed, or get a new one for free.
