Looks like GSM connectivity works which is a MAJOR breakthrough..
HTC Sense (HTC Desire base rom) v2
This build includes: Sound, 3D, G-Sensor, Light Sensor, Compass, Multitouch and high stability.
Radio/GSM and 3G connection is now functioning.
Note: To enable sound, run CLRCAD.exe before you run HaRet.exe
Thanks to everyone at #htc-linux for your help and support! Without you, there would be no Android on the HD2 🙂
