goto htc's dev site google htc unlock should take you to htc's unlock site... follow the instructions there to unlock.
ROOTING the design is not hard, its just awkward, like lighting a cigarette in a rain storm, it can be done.
when 2fastroms comes back online grab the ClockWork mod for the "HTC hero one / kingdom" (which is what our designs are called), then... rename the clockwork mod to PH44IMG.zip (make sure windows doesn't add a extra .zip to the extension) copy PH44IMG.zip to the root of your sd card, and drop to recovery mode (volume down on reboot).
it should load the PH44IMG.zip and reflash... done.. NOW this is what i learned, i thought it didn't take for like a week till i rebooted with volume down and selected "recovery" and no shit there was clockwork.
MAKE A BACKUP!!!!
(every time you flash a new rom backup then wipe and THEN flash new rom)
through the clockwork recovery flashing menu, flash this file off the memory card su-bin-3.0.32-efghi-signed.zip <--- google that (can't remember where i got it from) that is the SuperUser (SU is just like using su or sudo in linux), once that is installed then you can install one touch root, busybox, etc... because after SU is installed your pretty much done, its unlocked, and rooted... it doesn't sparkle or anything fancy or magically turn everything into bacon. But, you can flash some of the CyanoGen mods, most of the ones i tried were off of 2fasts's site which is down till he pays the bills. BUT, a cool but, is you can now change your bootscreens....
as far as apps go, Superuser (from the play store) automates the su process, rom manager is a good one to grab, you can pick the rom to flash and set it to make a back up before it reboots the phone and flashes the rom in recovery... pretty slick.
