The software on your phone is warrantied just like the hardware, and if you modify either part, you (typically) void your warranty. I don't get why this is even an issue. I get that some things are not black and white, but when it comes to a warranty, and something is explicitly stated will void yours, then it's pretty cut and dry.
I realize this thread is dead. However, I just had to chime in here. In the United States, rooting absolutely, positively, does not void your warranty. Your phone does not come with a software warranty. The software is provided as-is and without warranty, expressed or implied. Software warranties are usually relegated to enterprise and are irrelevant to this discussion. Physically opening an Xbox and running a program as root are not comparable. The previous poster (I7777) was correct. Warrantors (manufactures providing a warranty) cannot set whatever terms they choose for providing warranty service. If HTC sent you a document stating that you understand that any unauthorized software modifications void your warranty and you signed it, rooting your phone still wouldn't void your warranty. Warrantors have to comply with the Magnuson-Moss Warranty Act enacted in 1975. One of the requirements for Warrantors was described by I7777. Manufactures have to prove that your actions caused the defect in order to deny you warranty repair or replacement. There's a reason why HTCDEV unlock states that "unlocking your bootloader may
void your warranty". If it did unequivocally void your warranty I assure you, they would say so. I don't understand why this warranty misconception exist with phones to the extent that it does. Nobody would ever suggest that you risk voiding the warranty on your PC by running a program or operation that requires administrative privileges.
