Android Thoughts: HTC Super Tool Lets You Mess with HTC Devices, Including Rooting

"If you have a rather recent HTC phone, the manufacturer allows you to unlock its bootloader the official way; the procedure might involve a lot of steps and, in the end, you are achieving root on your device with the price of officially voiding your warranty."

A rather interesting way to get around the root issue on your phone, promising to let you root without officially voiding your warranty. However I'm pretty sure if you claim warranty service and they notice you're rooted, they'll void you anyway, so use at your own risk!
