When it comes to unlocking bootloaders, HTC has been on a roll. We recently reported the news of HTC allowing for all devices launched after September 2011 to be unlockable, and now, it seems they are adding more pre-Sepetmeber 2011 devices to their long list of supported devices. An unprecedented gesture of developer support if you ask me.

We now have answers as to why HTC Rezound users were able to unlock their device using the instruction from HTCdev.com. It appears any device launched after September 2011 is now unlockable and HTCdev will be updating the site accordingly. This is excellent news for the future of HTC and its customers.

HTCdev.com, the official site for unlocking your HTC bootloader, has inadvertently given HTC Rezound owners instructions on how to unlock their bootloaders. The HTC Rezound has yet to be officially listed on HTCdev.com but according to a few sources, the instructions for unlocking your bootloader also apply to the Rezound and will work if followed correctly. You will be left with S-On and will have to perform a factory reset at the end (so do a backup if needed).

You may remember us talking about the HTCdev site which helps HTC owners unlock their device’s bootloader. That site while “official,” takes quite some time to update its list of unlockable devices. That is why xda-developer forum user frigid decided to go ahead an create his own utility to speed things up. Picture the HTCdev unlockable list on steroids and that’s what you get with the unofficial HTC Super Tool.

Ahhh, the unlocked bootloader aka the keys to the kingdom. An unlocked bootloader may or may not mean anything to you depending on your level of OS involvement, but having one “unlocked,” is always a good thing in my book. HTC also understands the importance of unlocked bootloaders, and how they help the developer community. This is why they started allowing users to “unlock” their device bootloader via the HTCdev website. Every so often HTC adds a new device to the official list and provides instructions on how to unlock it. Today, HTC has added two new devices to that list: the EVO View 4G and the MyTouch 4G Slide. Users of either of these devices now have an official way to unlock their bootloaders and begin tinkering with their device. So what exactly does “tinkering” mean, and is it something I want to do?
