The Sensation4G received its own unlocked bootloader from HTC a few days ago, today its the Evo3D's turn. HTC just today kept their promised, and made the EVO3D finally unlockable using their web-tool. This same treatment was delivered to their Sensation4G a few days ago, and left the T-Mobile users rejoicing about the simplicity.

HTC plans on keeping the train going and unlocking other newer model devices that they shipped with their advanced bootloader.
