We mentioned a few days back about the online HTC bootloader unlocker coming soon. Well now it has actually gone live.
The only device you can unlock for now is the HTC Sensation for EU users. HTC say they will be adding more and more models as time goes on so check back often to find out if your device is on there. From what it looks like the next two devices which you will be able to unlock are the HTC Evo 3D and HTC Sensation 4G, both for US only.
For those who don't know what unlocking your bootloader does. It lets you have access to root level of your device, the side of your device which manufacturers usually don't let you go near because they like to control their devices. Once you have unlocked your bootloader, you can then start using add ons such as ROMs and take complete advantage of your device. It is for advanced users to be careful if you don't know much and do your research.
Head over to the site now to unlock your bootloader on the HTC Sensation. (Note: EU users only)
