Before you proceed to the rooting instructions below, please read this disclaimer:
XDA-DEVELOPERS.COM and I are not responsible for what you are doing to your device. You understand and agree that you are doing this at your own risk.
as for warranty the rule of thumb is if you root you should always consider your warranty voided : i will make no claim otherwise on the subject.
i am just a simple hobbyist from Cinti. OH USA i have no intention to buy devices or users getting mad that they were under some impression this wouldn't void the warranty.
