HTC have posted an update on their Facebook page about the status of officially unlocking the bootloaders on their Android devices. They are making it available via a web tool and stating that it could void your warranty.  Fare I guess! Check out the post below:
**UPDATE 8/3/2011**
 Since our last update, many of you have asked how the bootloader unlocking process will actually work, and in particular why HTC’s most recently released devices still have a locked bootloader. Rest assured we’re making progress toward our goal to roll out the first software updates in August to support unlocking for the global HTC Sensation, followed soon by the HTC Sensation 4G on T-Mobile and the HTC EVO 3D on Sprint. Because unlocking the bootloader provides extensive control over the device and modifications may cause operation, security and experience issues, new devices will continue to ship locked but will support user-initiated unlocking using a new Web-based tool.
So how will this work? The Web tool, which will launch this month, requires that you register an account with a valid e-mail address and accept legal disclaimers that unlocking may void all or parts of your warranty. Then plug in your phone to a computer with the Android SDK loaded to retrieve a device identifier token, which you can then enter into the Web tool to receive a unique unlock key via e-mail. Finally, apply the key to your device and unlocking will be initiated on your phone.
We’re excited to bring bootloader unlocking to developers and enthusiasts, and we feel this new Web tool will meet your needs and continue to provide customers with the best experience. Thanks to the community for supporting these efforts!
While your waiting for the official unlocker web site to go live, the amazing developer community that exists today has already provided it’s very own method. Unlock you HTC Sensation and the EVO 3D and flash away the community goodness. To find the latest releases for these and all other Android devices, head over to Commuity Release.
