It seems that a group of eager folks at XDA grabbed the device, ran home, and gave HTCdev.com a shot. HTCdev allows you to easily unlock your bootloader. Unlike Nexus devices that can be easily unlocked and relocked via fastboot, you need to generate a token with HTCdev marking your device as bootloader unlocked and killing your warranty. For now you can choose "other devices" at HTCdev.com and unlock your Verizon HTC One. I have a feeling that Verizon will soon coerce HTC into blocking their device on HTCdev. That being said if you want an unlocked bootloader you should go do it NOW!
