The HTC EVO 3D has only had S-OFF for several days, but it looks like some enterprising developers might already have an early port of CyanogenMod 7 available for the EVO 3D very soon.
Developers already have a working version of CM7 on the EVO 3D's cousin, the HTC Sensation 4G, so the EVO 3D is most certainly right around the corner. CM7 is the AOSP ROM of choice for many people, remaining as close to stock, unaltered Gingerbread as possible, while also offering some valuable enhancements.
While we are still likely weeks or months away from a stable release on the EVO 3D, nightly test builds should be available any time now. So while you wait in steadfast anticipation, take a look at the video below for a teaser of CM7 on the Sensation 4G.
Update: It looks like an early port of CM7 is floating around out there for the EVO 3D right now. No word on when it will be ready for public release, but you can see the video evidence below.
