Rooting is good after your contract ends and you want to still be able to use your c-phone to the fullest. Some cell phone service disable your phone entirely when contract is not renewed. Since you paid hundreds of dollars for the phone embedded in the "contract" deal why shouldn't you be able to still use it after the contract ends? Hence, this is when rooting come in handy: rooting would remove whatever restrictions there might be preventing you from using your cell phone features like the camera, calendar, email using wifi if you have a smart phone, etc. There should be law allowing and enabling you to what you want to your c-phone after the contract period ends--you paid for in full; you own it and should be able to use as you like. This is one reason to root the phone--especially for the iPhone owners: to be able to use the camera, listen to your music, etc. A lot of the older iPhones are sold and rooted for resale at a cheaper price and a lot of people buy them in the black market.
