The point we like to discuss here is why do Jail breaking voids your warranty. Why it is against the terms or Apple.
Many people will have this doubt in their mind. What If I jail break my Apple iPhone and something goes wrong, will my warranty cover it?
I would just like to tell something to such people. Jail breaking voids your warranty. It is against the terms and conditions of Apple. Because it allow the user to access the root of the device and also the ability to install pirated apps, among other things.
And it also violates the software license agreement that you agree to when purchasing the Applie iPod touch, iPhone or what ever you agree not to.
