No matter which HTC EVO device you own, and no matter how many OTA updates you have taken, there is now officially nothing stopping you from rooting your phone. This is all thanks to HTC Supertool, a new method of rooting almost all HTC Android devices, and it's been confirmed to work on the HTC EVO 4G, the EVO 3D, the EVO Design 4G, the EVO View 4G, and even the red-headed stepchild better known as the EVO Shift 4G.
In addition to unlocking the bootloader and rooting your phone, this tool offers additional options to "De-Sense" your phone, re-enable Sense, unroot your phone, relock the bootloader, enable wireless tethering, and flash a new(er) version of the Android Market.
I can't personally test this on my EVO View tablet, as it's currently out for repairs. And my EVO 3D is already rooted and running Fresh 4.1.0 (a great ROM, by the way!). But if you have held off on rooting until an easier method were to come along, this might be just what you're looking for.
