You means besides your Evo?
This is all blog nonsense, again and again.
HTC's bootloaders have been locked for some time - and signed.
That's the way it was with the Evo at launch, and the way it still is - and is for other HTC phones, like the Shift and Thunderbolt - locked and signed.
They are not encrypted, there is no evidence that they'll ever be encrypted, and all this hoopdee is because blog writers feed on each other - one bit of mis-info, and it gets propagated.
Ever do that thing back in school where you like some kids up, the teach whispers a story to one, and says pass it on, and then compare the end result to what the teach told in the first place?
It's like that with blogs.
We've done all we can to correct them, but until the writers panicking about HTC bootloaders have time to understand the tech, they discount the facts as opinions as good as their own.
