Jailbreak surely can't prevent SO from being disabled. Remember, Amazon isn't a warden, so it doesn't watch for any your action, and jailbreak doesn't have anything common with real jail, so there will be no punishment for applying it. OTOH, speaking about technical side, jailbreak just doesn't touch anything related to SO disabling.

After paying, you can do it by yourself in any time at Amazon's "Manage Your Kindle" page.
