Welcome to the party, dx users have felt this hate for almost a year now. But htc obviously cares for us, not enough to give cyan a dev device, but they promised unlocked bootloaders for US, and i think if you remind them that they have created a beautiful device with amazing possibilities, they'll update it with the unlock key. They did mention that they already had updates made without unlock keys before they changed policy, so its a bit of a delay, seeing as how they have to reassemble those updates.
So hang tight, i think htc has you guys coming up soon
Oh and keep in mind, they are worldwide and run on android & windows mobile. They have A LOT of phones and users to tend to. They work hard for us, dont worry
