Replicant developer (more accurately, someone allowed to call myself one)
here. Unfortunately, the Galaxy S and Star are not the same device.
If you want Replicant support for the device, it needs to have CyanogenMod
support first. But the existing CyanogenMod developers don't take device
requests. You can try a port yourself by looking at their porting guide.
The good news is, this device actually looks it would be a good target for
Replicant if there were CyanogenMod support. I'll have to ask Paul the lead
developer about that.
Finally, you should know that the Replicant project itself has forums for
questions like these! See
